90multipath: install dracut-specific service file

The multipathd package might install a service and a socket
file. Using the original service file from the installed
system without the socket file triggers a bug in systemd,
causing systemd to crash.

As we don't actually need to socket file in the initrd we
should be installing our own service file which does not
reference the socket file at all.
