intel: Enable S3TC extensions always

Always enable the use of pre-compressed texture data.  The ability to
perform on-line compression still requires the presence of libtxc_dxtn
or an explicit driconf over-ride.  Applications that just want to submit
precompessed data when an on-line compressor is not available can look
for the GL_EXT_texture_compression_dxt1 and
GL_ANGLE_texture_compression_dxt[35] extensions.

v2: Only enable the extensions that do not require on-line compression
by default.  The previous statement "This should not impact many (if
any) real applications." proved to be false for at least Sauerbraten.
This application mostly submits pre-compressed data, but it also can
submit uncompressed data that it asks the driver to compress.
