Drop ebuild patches

None of these are necessary anymore.  They do not apply cleanly to
current versions of ebuilds in Gentoo's repository, causing builds to
fail.

Going forward, I think it will be better to maintain patched ebuilds in
the Aimee OS repository, rather than patching them at build time.
