This is a different way to implement the fix proposed by commit
a4021390fe suggested by Lennart Poettering.
In this patch we instruct PID1 to not kill "systemctl switch-root" command
started by initrd-switch-root service using the "argv[0][0]='@'" trick.
See: https://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons/ for
more details.
We had to backup argv[0] because argv is modified by dispatch_verb().
