mesa: Fix dlopen failures due to TLS model

Switch to global-dynamic TLS model with gnu2 dialect.

The use of the initial-exec TLS model requires non-standard
arrangements by the loader, only implemented by glibc, and additionally
causes dlopen of libGL to fail under several circumstances.

By using the gnu2 TLS dialect, the global-dynamic model becomes
as efficient as initial-exec in most circumstances, and works with
reduced performance where initial-exec prevents loading altogether.
