bootloaders: change 'Advanced options' to 'Utilities'

more fitting now that we've moved the advanced installer entries
out to a different submenu, leaving just memtest (and HDT on
syslinux).

the advanced.cfg file is also renamed to utilities.cfg in the syslinux
case, but in a backwards compatible way of moving the user advanced.cfg
file over the new one, if the user provides a file with the old name.
alternatively we could just leave the old name in place, but that would be
a little odd.
