UTIL: Add a utility function sss_output_name

Adds a convenience function that will help reduce the amount of code
duplication in the responders. All responders need to parse the username
from the internal format, lower-case the name, if the domain is
case-insensitive and then replace spaces if the responder is configured
to do so.
