selftest/reproducible: Print full log path on failure

Printed message looks like this:
2025-01-12 00:40:08,326 - oe-selftest - ERROR - reproducibleA build failed. Trying to compute built packages differences but the test will fail.
2025-01-12 00:40:08,326 - oe-selftest - INFO - Failure log for reproducibleA will be copied to <snip>/oe-reproducible-20250112-mza9w940/bitbake-reproducibleA.log

Fixes [YOCTO #15655] (first half).
