[LTP] [PATCH v2 1/1] tools: Fix syntax error caused by "; ; " in create_dmesg_entry awk script

[Shizhao Chen]

When running runltp with both -S and -K provided, tests that are supposed to be
"skipped" and report TCONF results were failing due to an unexpected semicolon
at the end of the constructed command.

`-S` replace the test command with `exit 32;`
`-K` appends another semicolon to the command then we get `exit 32;;`

For example:

  >>> 780:madvise06__with_dmesg_entry BROK <<<

       1        <<<test_start>>>
       2        tag=madvise06__with_dmesg_entry stime=1703556061
       3        cmdline="dmesg -c 1>/dev/null 2>&1; exit 32;; dmesg > /mnt/testarea/ltp/output/DMESG_DIR_RHELKT1LITE.FILTERED-dmesg-output-53127-08:48:23PM/madvise06.dmesg.log"
       4        contacts=""
       5        analysis=exit
       6        <<<test_output>>>
       7        sh: -c: line 1: syntax error near unexpected token `;;'
       8        sh: -c: line 1: `dmesg -c 1>/dev/null 2>&1; exit 32;; dmesg > /mnt/testarea/ltp/output/DMESG_DIR_RHELKT1LITE.FILTERED-dmesg-output-53127-08:48:23PM/madvise06.dmesg.log'
       9        <<<execution_status>>>
      10        initiation_status="ok"
      11        duration=0 termination_type=exited termination_id=2 corefile=no
      12        cutime=0 cstime=1
      13        <<<test_end>>>
