i965: Drop strict conformance fallback for GL_LINE_SMOOTH.

Browse source 
We do have hardware antialised lines.  If we care, we should actually
fix them to be conformant (or as close as possible) instead of using
this knob to fool testcases using swrast.

For some interesting reading on the state of GL_*_SMOOTH across
several drivers, see:
