Fix a nasty bug in eq_ufVar, which meant that unfoldings were
comparing equal when non-local names in the unfolding had changed,
which could lead to erroneously avoiding recompilation.

This bug could cause bad behaviour along the lines of "my program was
segfaulting, but I did make clean; make and now it works!".
