glx: Retrieve the value of RENDER_TYPE from GLX attribs array

Make sure that context creation routines are provided with the value of
RENDER_TYPE retrieved from GLX attribs.

v2 (idr): Minor formatting changes.  Change type of
dri2_convert_glx_attribs render_type parameter to uint32_t to silence
some GCC warnings.
