nspawn: allow --setenv=FOO as equivalent to --setenv=FOO=$FOO
systemd-socket-activate has supported such a mode since
5e65c93a433447b15180249166f7b3944c3e6156. '--setenv=FOO=$FOO' is a fairly
common use in scripts, and it's nicer to do this automatically without worrying
about quoting and whatnot.
https://github.com/systemd/mkosi/pull/765 added the same to 'mkosi --environment='.
