description:
Include mesa-ver.mk so MESA_VER doesn't get expanded into an empty string.

This changes the output of glGetString(GL_VERSION)
from: 3.1 Mesa
to: 3.1 Mesa 18.3.4

This means programs like firefox/libreoffice no longer blacklist our mesa
version as being too old.

Fixes WebGL on firefox with AMD CEDAR, reported by nia.
