Add sysrc(8) support for "rc.conf.d" file(s) when given "-s name" to
indicate service(8) script. While here, add "-l" option for listing the set of configuration file(s) considered (in order; separated by space). Also add "-L" for exploring all configuration files and "-E" to omit files that don't exist from operations.
