fstests: GDBM detection cleanup

From: Jeff Mahoney <[email protected]>

Commit 2353022 (build: update AC_PACKAGE_WANT_GDBM() and src/dbtest.c to build) fixed building on newer SUSE systems but broke older ones. Where we used to skip building src/dbtest on SLES systems, now we'd fail to build on SLES11. The reason was that we were now detecting ndbm.h but also including gdbm.h, which doesn't work on older systems due to both defining the datum type. It turns out that no system needs gdbm.h at all.

This series cleans up the macros and fixes detection for all systems that only have /usr/include/ndbm.h.
