Replacing grubby with grub2-mkconfig in kernel install process

Having two completely different ways (grubby fiddling with it directly
vs. grub2-mkconfig) to update the grub2 configuration sucks big time
IMHO.  It's inconsistent once both tools touched the config.  It also
asks for trouble, for example if there are any grub2-mkconfig changes
which generate config files grubby can't parse correctly.  With grub2
config essentially being a script language this can easily happen I suspect.

Just have grubby call grub2-mkconfig to update grub2.conf and be done
with it.

cheers,
