x11-drivers/xf86-video-intel: Block <media-libs/mesa-12.0.4 for dri3.

Mesa 12.0.4 contains commit 17f59da9dbf ("loader/dri3: import prime
buffers in the currently-bound screen"), which is a cherry-pick of
commit a599b1c2037 from the master branch. This commit fixed the bugs
noted in the ewarns removed by this patch, which affected DRI3
stability.
