95rootfs-block: Correctly terminate commandline parameter

95rootfs-block would not terminate the commandline parameter with
a space or newline, instead it'll rely on the main routine from
dracut.sh to do this.
Which will cause unexpected problems for any modules called
after this.

So terminate the commandline parameters correctly here and remove
the newline from dracut.sh.
