Subject: [PATCH] Check only (no longer test) at the MSRV

Adjust CI so we only run a check the main crate at the MSRV (1.23),
running tests only at the MSRV of test dependencies. This allows us to
keep CI passing without increasing `glob`'s MSRV to match that of `libc`
(which since recently is 1.63.0) or other test dependencies.

Additionally, set `rust-version` in Cargo.toml.
