depends: libX11: Make package headers-only

We're no longer building QT with libX11/XLib, however, libX11/XLib
headers are still required for parts of QT. In this commit we add a
minimal configure.ac for libX11/XLib that is headers-only.

This change allows us to remove all of libX11/XLib's dependencies.
