github-actions: Add cargo-deny

Adds cargo-deny to scan for vulnerabilities and license issues regarding
rust crates.

Some modifications were required for the repo to pass the tests:

 Updates ttrpc to avoid using nix 0.16.0
   https://rustsec.org/advisories/RUSTSEC-2021-0119

 Updates slog-json to avoid MLP license (copyleft)

 Updates crossbeam-channel because 0.52.0 was a yanked package

 Ignores https://rustsec.org/advisories/RUSTSEC-2020-0071
   because chrono is dependent on that version of time.
   chronotope/chrono#578

 Allow multiple versions of the same package
  (package dependencies require this)

 Adds "oci" to src/libs workplace

 Adds Apache-2.0 license to workplace modules that did not have them
 because cargo-deny complains about them not having licenses.

Notes
GitHub Actions does not have an obvious way to loop over each of the
Cargo.toml files. To avoid hardcoding it, I worked around the problem
using a composite action that first generates the cargo-deny action by
finding all Cargo.toml files before calling this new generated action in
the master workflow.

Fixes kata-containers#3359
