Fix plymouth passphrase prompt with dracut

plymouth --command splits the command on spaces which means that zfs-load-key was getting the filesystem name enclosed in single quotes (since 13c59bb) 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).
