nftables: Fix ptest output format issues

Fix the following ptest output format issues:

-   For "sed" command, change "-e" option to "-E" option. I believe the
    previous "-e" option is a typo based on the manual page of "sed":

        -e script, --expression=script
            add the script to the commands to be executed

    "-E" option, on the other hand, makes "sed" "use extended regular
    expressions in the script" according to the manual page.

-   The test result summary line is being treated as both a passed
    testcase and a failed testcase due to this line containing substring
    "[OK]" and "[FAILED]". The following is a sample test result summary
    line:

        I: results: [OK] 379 [SKIPPED] 1 [FAILED] 0 [TOTAL] 380

    The fix is to change run-ptest to look for "I: [OK]" and
    "W: [FAILED]" when determining which lines correspond to
    passed/failed testcases.

-   Previously, only "W: [FAILED]" out of the following testcase failure
    prompts is parsed:

        W: [CHK DUMP]
        W: [VALGRIND]
        W: [TAINTED]
        W: [DUMP FAIL]
        W: [FAILED]

    Adding parsing for all testcase failure prompts.
