Fix bug: When run Test_filejournal testcase with gtest argument, all of testcases...

when run testcase with gtest argument, for example, with argument --gtest_output=xml:/root/reports/ceph_test_cls_version.xml,
then the test result is failed, because of the test program use the first argument as the journal file name.
