shader: Emit the right GLSL function when dealing with TGSI_MEMBAR_ATOMIC_BUFFER

The GLSL spec does not mention a memoryBarrierAtomic function, and the
GLSL to TGSI compiler indicates that a TGSI_MEMBAR_ATOMIC_BUFFER is
created from GLSL's memoryBarrierAtomicCounter.

Ref: 526f7d7790/src/mesa/state_tracker/st_glsl_to_tgsi.cpp (L3737)
