[PATCH nft 10/11] tests/shell: record wall time of test run in result data

[Thomas Haller <thaller@xxxxxxxxxx>]

When running tests, it's useful to see how long it took. Keep track if
the timestamps in a "times" file.

Try:

    ( \
        for d in /tmp/nft-test.latest.*/test-*/ ; do \
               printf '%10.2f  %s\n' \
                      "$(sed '1!d' "$d/times")" \
                      "$(cat "$d/name")" ; \
        done \
        | sort -n \
        | awk '{print $0; s+=$1} END{printf("%10.2f\n", s)}' ; \
        printf '%10.2f wall time\n' "$(sed '1!d' /tmp/nft-test.latest.*/times)" \
    )
