After offline installation, scylla-jmx fails to be started for a chdir
error. WorkingDirectory is set to /var/lib/scylla in scylla-jmx.service,
it doesn't exist in nonroot install. This patch solved the problem by
setting WorkingDirectory to empty in nonroot.conf.
$ systemctl --user status scylla-jmx
