Support fake Java property overrides in function equality in bridges

A synthetic property descriptor created for `B.value` (see the added
test) should not be equal to the normal descriptor created by the fake
override construction algorithm. Otherwise we can't reach this synthetic
non-abstract descriptor when building bridges in `C`, which results in
exception.
