glx: fix regression for drawable type detection

Newer version of XServer supporting GLX_DRAWABLE_TYPE query also
support query with raw X11 window ID besides GLXWindow ID. So we
should not limit the suppported type to GLXPbuffer when query
success.

Otherwise can't start GLX application on newer XServer with:

  libGL error: GLX drawable type is not supported
  libGL error: GLX drawable type is not supported
  X Error of failed request:  GLXBadContext
    Major opcode of failed request:  149 (GLX)
    Minor opcode of failed request:  5 (X_GLXMakeCurrent)
    Serial number of failed request:  35
    Current serial number in output stream:  35
