Prevent plymouth-start.sh from creating already existing device nodes.

Prevent messages such as the following when booting dracut:

++ mknod /dev/null c 1 3
mknod: `/dev/null': File exists

The plymouth-start.sh script tries to create device nodes it needs, but which
have already been created by the /init script.

This patch makes the mknod calls conditional.
