pkg-config files list protos when not required

[Jeremy Huddleston]

Why do the pkg-config files still report that the protos are dependencies of the Xlib libraries?  Shouldn't that have been removed with the big proto/Xlib cleanup prior to the last Katamari?  Was this just overlooked or intentional?  I don't see any reason why a userland application building against libX11 should require xproto.
