cleanup: Remove RPM openvpn.spec build approach

Linux packaging is quite a comprehensive task these days, with many
Linux distributions and each with their own packaging guidelines.  In
addition OpenVPN is packaged for most important Linux distributions
already.

The OpenVPN developers is not capable of keeping track of how all the
various recommend packaging guidelines evoloves and our RPM build
process is no longer consistent with guidelines from Fedora, RHEL or
SUSE packaging.  We also don't receive any updates improving this
situation.  Most likely due to packaging being handled fairly well by
the Linux distributions directly.

In addition comes systemd into play, which more and more Linux
distributions embraces - and even our own RPM openvpn.spec file didn't
account for that move.

This removes all RPM related packaging files and updates the INSTALL
file with pointers to several popular Linux distributions with
accessible information of the OpenVPN packages they provide.  Linux
distributions is most likely much better at keeping the packaging
up-to-shape much better than we.

-BUILDING ON LINUX 2.6+ FROM RPM
+Linux distribution packaging:
 
-You can build a binary RPM directly from the OpenVPN tarball file:
+Each Linux distribution has their own way of doing packaging and their
+own set of guidelines of how proper packaging should be done.  It
+is therefore recommended to reach out to the Linux distributions you
+want to have OpenVPN packaged for directly.  The OpenVPN project wants
+to focus more on the OpenVPN development and less on the packaging
+and how packaging is done in all various distributions.
 
-	rpmbuild -tb [tarball]
+For more details:
 
-This command will build a binary RPM file and place it in the system
-RPM directory.  You can then install the RPM with the standard RPM
-install command:
+* Arch Linux
+  https://www.archlinux.org/packages/?name=openvpn
 
-	rpm -ivh [binary-rpm]
+* Debian
+  https://packages.debian.org/search?keywords=openvpn&searchon=names
+  https://tracker.debian.org/pkg/openvpn
 
-When you install the binary RPM, it will install
-sample-scripts/openvpn.init, which can be used to
-automatically start or stop one or more OpenVPN tunnels on system
-startup or shutdown, based on OpenVPN .conf files in /etc/openvpn.
-See the comments in openvpn.init for more information.
+* Fedora / Fedora EPEL (Red Hat Enterprise Linux/CentOS/Scientific Linux)
+  https://apps.fedoraproject.org/packages/openvpn/overview/

-Installing the RPM will also configure the TUN/TAP device node

+* Gentoo

+  https://gitweb.gentoo.org/repo/gentoo.git/tree/net-vpn/openvpn
 
-Note that the current openvpn.spec file, which instructs the rpm tool
-how to build a package, will build OpenVPN with all options enabled,
-including OpenSSL, LZO, and pthread linkage.  Therefore all of
-these packages will need to be present prior to the RPM build, unless
-you edit the openvpn.spec file.
