Separate type for chronyd config file.

Separate label for /etc/chrony.conf (chronyd_conf_t) with interfaces to allow read-only or read/write access.  Needed as I have a process that alters chrony.conf but I didn't want this process to have access to write all etc_t files.

Fixed summary for chronyd_rw_config interface from previous submission.
