Install cmake to restore lintcheck runs (#14514)

`tokio-rustls` requires `aws-lc-sys` which requires `cmake 3.x` to be
built. This installs `cmake 3.x` from the repository, overriding the
`cmake 4.x` installation.

The situation will be reexamined in a few weeks, as `aws-lc-sys` will
get a new release in a few days with `cmake 4.x` support. We will then
be able to remove this temporary fix.
