execute_process: Improve COMMAND_ERROR_IS_FATAL error capture scenarios

1.  COMMAND_ERROR_IS_FATAL ANY will capture errors if the exit code is
    non zero, there is a timeout or an abnormal exit.

2.  COMMAND_ERROR_IS_FATAL LAST
    will capture if only the last process has an exit code non zero, there
    is a timeout or an abnormal exit.

Fixes: #21562
