Issue found on Focal 5.4.0-1008.9 GKEOP

This is what you will see when trying to install linux-gkeop on Focal:
$ sudo apt install linux-gkeop
Reading package lists... Done

The following package was automatically installed and is no longer required:

BTW,
with the module extra package installed, the following command will print two entries
  $ grep menuentry /boot/grub/grub.cfg | grep -F gkeop | grep -v recovery | awk {' print $15 '} | sed "s/'//g"
  gnulinux-5.4.0-1008-gkeop-advanced-dc7ce673-d33f-4a3b-bce1-fff7064b9ab4
  osprober-gnulinux-/boot/vmlinuz-5.4.0-1008-gkeop--dc7ce673-d33f-4a3b-bce1-fff7064b9ab4

This will cause boot-kernel-simple to select the wrong kernel to process (these two will be combined together)

Without the module extra package, there will be just:
  gnulinux-5.4.0-1008-gkeop-advanced-dc7ce673-d33f-4a3b-bce1-fff7064b9ab4

I think maybe we can change the grep target "gkeop" to "gkeop-advanced"

Test shows change the grep target "gkeop" to "gkeop-advanced" is still working for B-5.4-gkeop.
