Allow overriding the systemctl command for sysroot with $SYSTEMCTL
Modified every modules' module-setup.sh to use the envvar instead
of the hardcoded command name.

On my system the following initrd-release is generated:
...
VERSION="4 dracut-048 dracut-048"
...
VERSION is not defined in /etc/os-release, so the variable is
concatenated with its previous value:
* "4" comes from the kernel build system since dracut is called from the
kernel install hook ("4" is a major kernel version);
* first "dracut-048" comes from the "systemd-initrd" module;
* second "dracut-048" comes from the "base" module.
Basic systemd functionality is in 00systemd now.
Switching root and the initrd.target is in 00systemd-initrd.
Dracut additions to the systemd initrd are in 98dracut-systemd.
