Subject: [PATCH 1/2] Switch CI's minver check to use -Zminimal-versions

Using -Zdirect-minimal-versions now fails due to an indirect dependency
(futures-util) now depending on a direct dependency (futures-channel).
-Zdirect-minimal-versions brings in the latest version of every indirect
dependency, which conflicts with bringing in the oldest version of
futures-channel.

A complicating factor is that every version of futures-util from 0.3.0
to 0.3.30, inclusive, has been yanked.  Unwisely, IMHO.
