ktest updates for v7.1:

- Fix month in date timestamp used to create failure directories
 
   On failure, a directory is created to store the logs and config file to
   analyze the failure. The Perl function localtime is used to create the
   data timestamp of the directory. The month passed back from that
   function starts at 0 and not 1, but the timestamp used does not account
   for that. Thus for April 20, 2026, the timestamp of 20260320 is used,
   instead of 20260420.
 
 - Save the logfile to the failure directory
 
   Just the test log is saved to the directory on failure, but there's
   useful information in the full logfile that can be helpful to analyzing
   the failure. Save the logfile as well.
