For consistency with other Racket distributions, 'racket-minimal' should
have the "racket-lib" Racket package installed: see
<https://github.com/racket/racket/issues/3851#issuecomment-942368947>.
Happily, this gives us a clean boundary between the core Racket VM and
compiler, with all of the bootstrapping involved, and building Racket
packages and installation layers, which can be handled in a nice,
uniform way and eventually turned into a 'racket-build-system'.
Building the VM layer as an "in-place" installation should help us use
it with other Racket tools.
