rc-once/systemd: fall back to the rescue boot-target if rc-once fails to remount RW
In cases where the root filesystem medium has some kind of external
write protection (like an SD card has), remounting the root filesystem
read-write fails and the system seems frozen, because systemd never
starts any log-in console.
This change forces the rescue target for this special case.
