When a requirement is specified like:
satisfy { which "foo" }
There is no reason that we should inject all of ENV.userpaths! into the
build environment. Instead, infer the directory to be added to PATH from
the Pathname that is returned.
This is another step towards condensing the "which program" requirements
down into a one-liner DSL element.
