Fix plymouth passphrase prompt with dracut

Browse Source 
plymouth --command splits the command on spaces which means
that zfs-load-key was getting the filesystem name enclosed
in single quotes (since 13c59bb76) and failing. This commit
fixes it by piping the password directly to the command
similar to how it's done in other scripts (initramfs,
dracut without plymouth).
