create MR for raur to support rusttls, and then use this feature in RUA

[vn971]

subj. Using rusttls seems to make sense as it is a mostly-Rust library that is a drop-in replacement of the current openssl dependency.

Thing is alpm itself depends on openssl. So either way you'll still have to have it installed.

@Morganamilo yes, that's true. I know that. Still wanted to make the change though.

Right now, lzma (xz) and alpm are left as linked dependencies. I want to switch to a pure-Rust version for lzma as well in the future, which would only leave alpm.

Regarding alpm, I'm really not sure. If it'll be gone, it will be possible to even statically build rua with musl. Do we need it though? IDK.
