[PATCH] grub-install-common: Fix the key of the --core-compress option

[Ákos Nagy]

Commit f23bc6510 ("Transform -C option to grub-mkstandalone to
--core-compress available in all grub-install flavours.") declared a new
long option for specifying the compression method to use for the core
image.

However, the option key has not been replaced in the parser function, it
still expects the old one formerly used by grub-mkstandalone. Because of
this the option is not recognized by any of the utils for which it is
listed as supported.
