Allow execution of chronyc from commandline

 With the previous patch moving chronyc into a separate domain this adds interfaces to execute chronyc from the command line and have it run in the chronyc_t domain.

Updated interface names based on suggestion, added missing permission to allow chronyc_t domain access to tty.
