mozjs-78: Set X lib/include paths

mozjs does not really use X but arcane autoconf 2.13 means its poking at
build host for X headers and libraries. On build hosts where X is
installed this results in wrong paths being searched for target X
headers, this gets caught by configure QA and it fails

ERROR: mozjs-78-78.15.0-r0 do_configure: QA Issue: This autoconf log indicates errors, it looked at host include and/or library paths while determining system capabilities.
Rerun configure task after fixing this. [configure-unsafe]
ERROR: mozjs-78-78.15.0-r0 do_configure: Fatal QA errors were found, failing task.
