Brian C. Lane b47554d716 livemedia-creator: Add support for reqpart kickstart command 
reqpart can be used to make kickstarts more platform agnostic, creating
needed partitions without lmc having to keep track of the arch-specific
needs. eg. ppc64 needs prepboot and /boot

This increases the size of the disk based on whether reqpart or
reqpart --add-boot is in the kickstart.

Note that this is only valid for partitioned disk output types, not
for filesystem images or live iso output.
