Install Vala bindings into system vapi dir

With this patch, a standard ./configure --enable-vala && make && make install will cause Vala bindings to be installed in VAPIDIR (usually /usr/share/vala/vapi).

Secondly, I changed the name of rb.vapi and rb.deps to rhythmbox.vapi and rhythmbox.deps. That's because every other .vapi I have ever seen has an identical basename to the pkg-config file. Since Jonathan named it rhythmbox.pc, it makes sense (by Vala convention) to name it rhythmbox.vapi.

Also included, the .vapi has been fixed up to properly build from the out-of-tree headers. The .deps has been updated to add `rhythmbox', which makes it include pkg-config --cflags --libs when you specify --pkg=rhythmbox to valac.

It is now straightforward to compile and link your Vala plugin from out of tree.

I should be able to pull out the rename into a separate patch if desired. The other fixes are pretty much taken as a whole: without them, we don't really do anything with the Vala bindings; with them, we need to tell Automake how to ship the Vala bindings, and then fix the bindings so that they actually work out-of-tree.

Patch is from git format-patch.
