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.
