I've actually left the two other scripts on python2, since they're not
used in the build, and I don't actually know whether anyone's still
using them manually. Leaving them on python2 should be a sign to future
maintainers (assuming they're far enough in the future) that maybe
no-one's using them and they can just be deleted instead.

Host init verifier already checks that the names and number of
arguments for builtins are correct, but it can check more. This
change ensures that property expansions are well formed, and that
arguments that can be parsed on the host are correct. For example it
checks that UIDs and GIDs exist, that numerical values can be parsed,
and that rlimit strings are correct.
