test: skip fdstore tests if test-fdstore is not available

When the test suite is run in the "standalone" mode, the minimal
container might not contain the test-fdstore binary that's needed for a
couple of tests. Since installing systemd-tests into the minimal
container pulls in a lot of other dependencies, let's just skip the
affected tests instead to avoid this.
