[ostree: 34/70] libtest.sh: only check whether $(pwd) is empty once

    libtest.sh: only check whether $(pwd) is empty once
    
    test-sysroot.js runs libtestExec() twice, one of which is after
    creating non-hidden directories in $(pwd), so this check needs to be
    skipped the second time.
