logind: Support logind.conf.d directories in the usual search paths
This makes it possible to drop in logind configuration snippets from a package or other configuration management mechanism. Add documentation to the header of /etc/logind.conf pointing the user at /etc/logind.conf.d/*.conf. Introduce a new helper, conf_parse_many, to parse configuration files in a search path.
