Subject: [PATCH] CI: Pin cc for MSRV build

The `cc` dependency just stopped working for MSRV build with error

    error: package `cc v1.0.96` cannot be built because it requires
    rustc 1.63 or newer, while the currently active rustc version is
    1.56.1

Pin `cc` back to an earlier version for MSRV build.
