drm/ci: enable lockdep detection
We have enabled PROVE_LOCKING (which enables LOCKDEP) in drm-ci. This will output warnings when kernel locking errors are encountered and will continue executing tests. To detect if lockdep has been triggered, check the debug_locks value in /proc/lockdep_stats after the tests have run. When debug_locks is 0, it indicates that lockdep has detected issues and turned itself off. Check this value, and if lockdep is detected, exit with an error and configure it as a warning in GitLab CI. GitLab CI ignores exit codes other than 1 by default. Pass the correct exit code with variable FF_USE_NEW_BASH_EVAL_STRATEGY set to true or exit on failure. Also update the documentation.
