glproto: import from upstream Gentoo

No local changes made.  Needed with newer eselect-opengl.

This won't actually get merged until package.keywords gets
updated, and that is being done separately for atomicity.

BUG=chromium-os:11963
TEST=deleted x86-alex build; built from scratch; checked symlink; checked that the system booted
