tests: cp: fix always skipped nfs-removal-race.sh

* tests/cp/nfs-removal-race.sh: This test was invalid since v8.32
as we now use fstatat() rather than stat().  Also since commit
v9.0-66-ge2daa8f79 we leverage the errno from open(O_DIRECTORY)
to avoid a stat, so pass --no-target-directory to ensure fstatat()
is called.
Discussed in https://github.com/coreutils/coreutils/pull/161
