userdiff: add xdiff_clear_find_func()
xdiff_set_find_func() is used to set user defined regular expressions
for finding function signatures. Add xdiff_clear_find_func(), which
frees the memory allocated by the former, making the API complete.
Also, use the new function in diff.c (the only call site of
xdiff_set_find_func()) to clean up after ourselves.
