fix the bug of wrong shell condition and contains more distro

This commit fix the fowlling problem:
1. move SUPPORTED_DISTRO to SUPPORTED_RPM_DISTROS
2. fix the wrong ID of "Anolis" to "anolis" in SUPPORTED_RPM_DISTROS
3. change distro in function to local variable
4. rename is_supported_distro to is_supported_rpm_distro; print_supported_distro
to print_supported_rpm_distro
5. fix the bug of return value of is_supported_rpm_distro
6. contains ubuntu and debian release in print_supported_rpm_distro, and adjust the vmlinux search logic at the same time.
