Derek Higgins 4c674a2476 Use grub2-mkconfig if update-grub isn't present
update-grub doesn't exist on fedora so if the legacy grub config file is
being used use grub2-mkconfig instead.

Also slightly change the sed GRUB_CMDLINE_LINUX regex so that it will
match if the command line already contains entries.
