Remove zfs.h comments about GRUB

Browse Source 
Nobody is going to be bumping SPA_VERSION again, as OpenZFS has moved on
to feature flags.  Also, there is no requirement to keep GRUB
up-to-date, nor has that been happening.

The ZPL_VERSION could be bumped, but that would likely be handled in a
similar way, by adding filesystem feature flags.  In any event, we do
not need this comment, and we certainly don't need a reference to the
GRUB 0.97 source code in a Solaris tree.
