i965/gen7: Fix point sprite texture coordinate overrides.
This is exactly analogous to Eric's Gen6 change in commit
f304bb8a5d040d99db47a65813d216d11c66fb47. His explanation:
"We were assuming that the input attribute n to the FS was
FRAG_ATTRIB_TEXn, which happened to be true often enough for our
testcases."
