Apparmor - allowing the executives of several binaries

[Iey4iej3]

The current setting only allows TeX Live fonts to be loaded. We should also include the permission of running mktexpk, mktextfm, dvipdfm and mkofm for evince to view dvi files (https://www.tug.org/texlive/debian.html):

${MAINTEXDIR}/bin/x86_64-linux/mktexpk Cx -> sanitized_helper,
${MAINTEXDIR}/bin/x86_64-linux/mktextfm Cx -> sanitized_helper,
${MAINTEXDIR}/bin/x86_64-linux/dvipdfm Cx -> sanitized_helper,
${MAINTEXDIR}/bin/x86_64-linux/mkofm Cx -> sanitized_helper,

and also modify ubuntu-helper (I don't know what is the correct way to modify this file - there is no local file), adding

${dTEXMFDIST}/web2c/{,**/}* Pixr,
${MAINTEXDIR}/bin/x86_64-linux/* Pixr,
