Xpra: Ticket #2203: opengl fails with alpha on Ubuntu 16.04

Tested as part of #2198, the client output shows:

Error presenting FBO:
 XError: BadMatch

Turning off alpha with XPRA_ALPHA=0 xpra attach.. causes it to segfault instead!

gl info collected on Ubuntu 16.04 with virtualbox 3D enabled

What happens here is that the latest driver now passes the gl feature and sanity checks, but still crashes at runtime, so r22054 re-adds "VMWare, Inc." to the blacklist.

A better solution is now in #2204.
