st/mesa: don't choose DXT formats if we can't do DXT compression
If we call gl[Copy]TexImage2D() with a generic compression format
(e.g. intFormat=GL_COMPRESSED_RGBA) we can't choose a DXT format if
we don't have the external DXT compression library.
We weren't actually enforcing this before since the
pipe_screen::is_format_supported(DXT) query has no dependency on
the DXT compression library.
Now if we're given a generic compressed format and we can't do DXT
compression we'll fall back to a non-compressed format.
v2: use util_format_is_s3tc() function and add more comments about
the allow_dxt parameter.
Note: This is a candidate for the stable branches.
