format-code: ensure default used if no other found

The default format-code.sh provided by this repo is installed in the
WORKSPACE dir (which is not searched). Use the default script if no
other one is provided by the repo under test.

Tested:
- Verified default was run when no other was present
- Verified the one in the repo under test was used when present
