Github CI

This PR adds a Github Actions definition to build and test the three libraries in this repo. The actual tests are ran in an Arch Linux docker image with Rust installed, ensuring that libalpm exists in the testing environment.

I'm not sure why this action definition didn't kick in. You may need to activate something in Settings -> Actions.

I built on this PR and made my own CI here: https://github.com/Morganamilo/alpm.rs/commit/7708da02fb0ad3718a33a27576dd50f18fcbdc81. I'll probably merge this instead, not to ignore the work you did.

Basically it tests alpm against pacman-git as well as git.

Also no -Sy cause that;s a partial upgrade ;)

[fosskers]

~I have that -y in there to insure that the most recent Rust is pulled.~ Oh I see, you added -u too. Is that necessary?

[Morganamilo]

It is to avoid partial upgrades. Anyway are you happy with the other actions file. I've not touched them before so don't really know the best way to do things.

[fosskers]

I made some comments on the commit, but otherwise it looks good!

[fosskers]

Alright, looks good for now. It looks like your commits were picked up and ran by Github CI, so at least the definitions are right.

Oh, and you might want to use caching? This PR demonstrates it, it should work as-is.

[Morganamilo]

I thought it wasn't needed because alpm has very minimal dependencies. Enabling the generate feature does add to that but I still feel caching is not needed much.

[fosskers]

Gotcha. Yeah even without it, the deps build pretty quickly. All in all each CI run should take less than a minute.

[Morganamilo]

Merged the other file then, thanks for the help setting up CI.
