Apply patches to recognize boot options passed to NetBSD kernels.
Bump PKGREVISION to 1.  From Piotr Meyer in PR pkg/30384.

As GRUB 0.x is in maintenance-only status now, I assume there is no
chance to get them incorporated mainstream.  We'll keep them here
though, as they seem useful (could have really helped me in some
situations when needing to boot single user).
