These were apparently lost in the transition to livemedia-creator.
livecd-creator added them in it's code, and lmc based its live config
files on the the boot.iso configs which do not include it (on purpose).
It never used vesa directly, it passes nomodeset, so make it less
confusing. Also simplify the menu text so that it fits on the screen
for distributions with long names.
Seems petitboot can't properly parse the live image grub config on ppc, thus
booting fails on bare-metal. Fix the problem by removing the obsolete 32-bit
entries.
When using the template install command copying the same file to itself
shouldn't crash. Just log the error and continue.
Also copy the s390 configuration files for use with livemedia-creator
