mesa/tests: Add simple, dumb test for _mesa_program_state_string

After some discussions about the correct way to update
_mesa_program_state_string, I decided to make a unit test for the
function.  It turns out that the function didn't work quite the way I
thought.  The unit test proves that the code was already correct.
