Make sure the chroot scripts dir variable is not overwritten

We used `d` for both the chroot scripts dir and the host scripts dir,
which means the host scripts dir overwrites the chroot scripts dir
variable. This isn't a problem when there's only one script, but
becomes an issue when there's multiple scripts of the same type.
