Bug#789395: libdrm-nouveau2: pushbuf.c not found

[Ilia Mirkin <imirkin@alum.mit.edu>]

Ah, if you can't build your own mesa, then I'm going to play around
with it a bit more and just push it. A future mesa release will
include it... I'm fairly sure that this change is correct, even if I'm
not sure that it will address your particular situation.
