fix compilation error in futimens tests

[Bruno Haible]

On AIX 5.1, HP-UX 11, IRIX 6.5, Solaris 7 I get an error like this
from a testdir for module 'futimens':

cc -O -DHAVE_CONFIG_H -I. -I..  -DGNULIB_STRICT_CHECKING=1  -DIN_GNULIB_TESTS=1 
 -I. -I.  -I.. -I./..  -I../gllib -I./../gllib    -g -c test-futimens.c
"test-futimens.h", line 77: undefined symbol: AT_FDCWD
cc: acomp failed for test-futimens.c
*** Error code 2

AT_FDCWD is now only guaranteed by the 'fcntl-h' module.

This patch fixes the problem and also a couple of possible similar problems.

        Depend on module fcntl-h when AT_FDCWD is used.
