rc: move job expire flags to rc to fix initalization problem

See: https://forum.rclone.org/t/rc-rc-job-expire-interval-bug/11188

rclone was ignoring the --rc-job-expire-duration and --rc-job-interval
flags.  This turned out to be an initialization order problem and was
fixed by moving those flags out of global config into rc config.
