gnu: libxcb: Add a patch for PATH_MAX on the Hurd.
Followup to 214b9d500f1434f745c26c5d9f826615d754a3ce.
The PATH_MAX issue has been solved upstream so use their patch instead.
* gnu/packages/patches/libxcb-path-max.patch: New patch.
* gnu/local.mk (dist_path_DATA): Add it.
* gnu/packages/xorg.scm (libxcb): Adjust ‘fix-PATH_MAX’ phase to apply the
patch instead of substituting the source.
