Since dropping some NV_fragment_program opcodes (commits
868f95f1da74cf6dd7468cba1b56664aad585ccb, a3688d686f147f4252d19b298ae26d4ac72c2e08)
we can no longer parse all opcodes necessary for this extension, leading
to bugs (https://bugs.freedesktop.org/show_bug.cgi?id=86980).
Hence don't announce support for it in swrast.
(The rest of the infrastructure ranging from dead opcodes (TXP_NV) to
parsing condition codes along with the NV_fragment_program_option variable
in the context could probably nuked too this is just a minimal fix appropriate
for stable too.)
