configure: Add systemd detection to --with-init-script=check

Most distributions, including RHEL, have switched to systemd,
so we should detect it and act accordingly. This also means
that 'systemd+redhat' should be preferred to legacy 'redhat'.

Our witness for the check is the availability of the systemctl
command on the host.
