chrony: fix wrong option in the default config.
chrony: fix wrong option in the default config.

The option rtcfile in the default config conflicts with runit's stage 3.
Chronyd in RTC mode takes control of /dev/rtc to measure RTC drift.
Stage 3 calls hwclock -w, which messes up chrony's drift calculation.
Furthermore the current chronyd runit service needs the -s option
to effectively use the RTC feature.

See for more info:

Switch rtcfile to the rtcsync option, to be consistent with stage 3.
Example config file 1 sets the right 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.
