glamor: Work around GEM usage v2 

KMS drivers are not required to support GEM. In particular, vmwgfx
doesn't support flink and handles and names are identical.
Getting a bo name should really be part of a lower level API, if needed,
but in the mean time work around this by setting the name identical to
the handle if GEM isn't supported.

This fixes modesetting driver dri2 on vmwgfx.
