This looks fine to me.

The only system I have by hand that have both <gdbm.h> and <ndbm.h> but
not any <gdbm/[gn]dbm.h> is openSUSE Tumbleweed. Without this patch,
dbtest was not built on openSUSE, and was built successfully with this
patch applied. And dbtest is still built on RHEL6/7 and Fedora.

BTW, I'll queue patch 3 and this patch for next fstests release, while
other patches seem not necessary, I agreed with Dave that groups are not
for excluding tests, the required tools and environments should be
detected by tests and _notrun if not met. (The README change looks fine,
but it doesn't apply due to the "fsgqa-381" change, so I drop it too for
now.)

Thanks,
Eryu
