Comment out currently failing build definitions

This gets wlroots to build, but the transitive closure of files
depending on wlr_surface.c is actually pretty large. As more interfaces
are changed to use the new compositor design, their build definitions
will be uncommented.

This also includes a very basic test client/server, but this will be
removed later.
