[PATCH 07/11] tests: dump log contents on assert_log_contains failure

assert_starvation_detected and assert_boost_detected already dump the
log file before calling fail, but assert_log_contains does not, making
failures harder to diagnose in CI.  Add the same log-dump pattern so
the file contents appear in the output on any assertion failure.
