macARM detection: Additional robustness improvements

- guard against glcontext being null (can happen on old browsers
  running 10.7)
- Add opengl code into try / catch block
- Move texture check into the else block (otherwise an already
  detected arm machine might be degraded to intel once support
  for that texture is added)
