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.
