Always set the LIBGL_ALWAYS_INDIRECT environment variable to 1 if indirect rendering was requested.

All AIGLX drivers need that environment variable to return the correct set of extension strings. Other drivers probably ignore the variable, but setting it shouldn't harm in any case.
If we don't set this environment variable from inside compiz, we're breaking being restored from a session manager for users of those drivers.
