frr: T6746: add default entry for config debug file

A lot of services have dynamic debug capabilities which will be turned on by
creating a file in /tmp. These scripts have the path hardcoded and sometimes
accross multiple places (bad).

This commit introduces vyos.defaults.frr_debug_enable to get the path for the
debug file from a single location.
