fix dbtest build

At least on my x86_64 RHEL5 box, if gdbm-devel is installed, then the
xfstests build fails with:

gcc dbtest.c -o dbtest -g -O2 -DDEBUG -I../include -DVERSION=\"1.0.0\" -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -funsigned-char -fno-strict-aliasing -Wall  ../lib/.libs/libtest.a

This patch fixes it for me, but my userspace-fu is weak; does this look ok?
