lib/tdb: fix transaction issue for HAVE_INCOHERENT_MMAP.
We unmap the tdb on expand, the remap. But when we have INCOHERENT_MMAP (ie. OpenBSD) and we're inside a transaction, doing the expand can mean we need to read from the database to partially fill a transaction block. This fails, because if mmap is incoherent we never allow accessing the database via read/write. The solution is not to unmap and remap until we've actually written the padding at the end of the file.
