This function converts a path on the system to a path relative to the users home directory that it contains. The relative path is prefixed with the user's primary domain in the below format:
domain.tld:/public_html/cgi-bin/xyz.cgi
If the path is not contained within a user's home directory, the path is returned without modification.
