chrony: fix wrong option in the default config.
The current option rtcfile in the default config conflicts with runit's stage 3 shutdown script.
The stage 3 script calls hwclock -w, while chronyd in RTC mode wants to take control of /dev/rtc to measure RTC drift.
Furthermore the default chronyd runit service does not take advantage of the Linux RTC functionality with the -s option.
See for more info: https://chrony.tuxfamily.org/faq.html#_i_want_to_use_code_chronyd_code_s_rtc_support_must_i_disable_code_hwclock_code

To maintain compatibility with the stage 3 shutdown, switch rtcfile to the rtcsync option.
Example config file #1 already sets the correct options that work out of the box so use that example file instead of editing the annotated one.
Example config file #3 will instead be installed to /usr/share/examples.
