Remove duplicate GRUB command line entry

Browse Source 
Without this change DIB appends a second command line entry to the GRUB
config. This causes the original command line entry to be ignored
when Linux is booted.

The expected behaviour is that DIB appends to the existing entry as
it does for Ubuntu and SUSE.

Following discussion on the review, this also removes the distro specific
switch statement, as update-grub just calls grub-mkconfig, meaning that
there was nothing distro specific in the first place.
