BORG_EXIT_CODES=modern can be set to get more specific process exit codes

If not set, it will default to "legacy" (always return 2 for errors).

This commit only changes the Error exception class and its subclasses.

The more specific exit codes need to be defined via .exit_mcode in the subclasses.
