Fix occasional v62000/gtm8086 subtest failure due to recent gtm8699 addition (#260)

Fix recent gtm8699 addition to gtm8086 test. Previously gtm8699 code block could pick up PREVJNLLINKCUT errors from other concurrently running subtests in the syslog. Fix it to pick up only messages from this subtest.
