mesa: add back-door support for cylindrical texture wrap mode
If the texture priority field is 0.125 set the PROG_PARAM_BIT_CYL_WRAP
flag. The gallium state tracker will look for this flag.
This feature is only for testing purposes and may be remove at some
point. But if it's useful we could write a GL/Mesa extension to
expose it properly.
