Allow configure to detect whether ndbm.h or gdbm/ndbm.h is installed.
This allows dbmmodule.c to use either without having to add additional
options to the Modules/Setup file or make source changes.
(At least some Linux systems use gdbm to emulate ndbm, but only install
the ndbm.h header as /usr/include/gdbm/ndbm.h.)
