mesa does not include vaExportSurfaceHandle support for vaapi

[Peter Frühberger]

Ubuntu prepares to ship libva 2.1 and mesa 18.x for Bionic. Mesa misses one tiny patch to make modern AMD GPUs work with VAAPI on wayland / gbm / mir. We tried to get this into final 18.0 but was not yet accepted. The change itself is a minor. Without it a certain feature is not available.

The fixup was included in Mesa 18.0.1 - so if you rebase on upstream's stable point-release above patch would not be needed anymore.

we're probably too close to the release to get 18.0.1 merged, but it will come as an SRU

bionic has had 18.0.5 for a while now
