mesa-jjk: Import latest from ABS
mesa-jjk: Repackage things

Turns out our original ligbl-jjk wasn't that good, because we put gl.pc in there
but obviously headers were missing. Alo our mesa-jjk then would have been like a
little over 1MB or so, so better to get closer to ABS and have a correct mesa
package, still we just what we need.
