lib/replace: force to unset defines if check has failed

For HAVE_WORKING_STRPTIME and HAVE_INCOHERENT_MMAP we always want to have their defines unset as the code is using '#ifdef' rather than just '#if'. Setting them to 0 means #ifdef will succeed due to a difference how '#ifdef' and '#if' are working.
