softpipe: Add (fake) support for TGSI_OPCODE_INTERP_SAMPLE

Softpipe doesn't support more than one sample, so this function
implements the interpolation at sample 0 and adds a stub to make it
possible to interpolate at other samples.

As it is this makes the piglits "fs-interpolateatsample-*" pass, but
they only ever test sample 0 anyway.
