logging_test: fix compile warning from oe-sdk

Update the variable holding the return from getopt_long to
be int, matching the manpage expectation, to resolve the

      |            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  244 |                               &option_index)) != -1)
      |                               ~~~~~~~~~~~~~~~~^~~~~
