[bug#35081] [PATCH] gnu: Add emacs-protobuf-mode.

Attached is a patch to add emacs-protobuf-mode, a major mode for 
editing Protocol Buffer source files.

I opted to add it in protobuf.scm instead of emacs-xyz.scm because 
it comes bundled with the protobuf source, and thus can share a 
source field.
