Vendors a copy of https://github.com/eth-pkg/apt-deb-cache taken as of commit fd375b6. Invoking `apt-get` directly every run can sometimes be very, very slow depending on the runner. This uses `apt-get` to download `.deb` files upon a cache miss, then installs and caches them. I tested it out on this PR: RustCrypto/crypto-bigint#1289 Package install was about twice as fast even uncached.

I'm testing this out with a third-party action:eth-pkg/apt-deb-cache@v0.2.6It's small and simple enough though if it works we can just vendor it and modify it for our own purposes.
Edit: vendored here: RustCrypto/actions#60
