meson: Do not use GLX_USE_TLS on Android.

Browse source 
The asm code expects a specific kind of implementation, but Android
uses something different (emutls).

Turns out mesa has a fallback with pthread_getspecific, with an
optimizaiton if only a single thread is used. emutls also uses
getspecific, so lets just use the optimized mesa implementation.

Fixes: 20294dceeb "mesa: Enable asm unconditionally, now that gen_matypes is gone."
