Fix tracebacks when invalid regex exists in config

There is a nagios quirk that allows '*' as a valid value where otherwise an actual regex is required.

We do same hack in our regex resolving, so '^*$' is replaced with '.*'

This fixes "sre_constants.error: nothing to repeat" on debian default config.
