glretrace: Use GL_TIMESTAMP (if available) for CPU profiling.

The prior scheme of trying to continuously re-synchronize separate CPU
and GPU counters is doomed to always be unreliable. Instead, simply prefer
to use the GL_TIMESTAMP values for both GPU and for CPU profiling.

v2: José Fonseca: use glGet(GL_TIMESTAMP)
