Switch to xx-cargo

[dfunkt]

• removes a lot of additional configuration lines from the Dockerfile
• includes the workaround for the openssl-sys build issues with improper pkg-config setup
• for reference: xx-cargo: fix vendor for pkg-config and clang tonistiigi/xx#108 (comment)

Could also switch to use lld as the linker if wanted.

In my previous tests this needed to have very large package based installed to get it to work properly.
So large, that it took long for everything to install, and the cache grew a lot. Though it might make it more easier, it doesn't make it faster.

If that currently isn't the case, then it might be fine i guess (I haven't tested it out yet).

Did some testing myself:
https://github.com/dfunkt/vaultwarden/actions/runs/20623608272 (no cache, no xx-cargo)

1. Build times:
   
   a) (no cache, no xx-cargo) -> Total duration: 11m 56s
   b) (cache, no xx-cargo) -> Total duration: 9m 38s
   
   c) (no cache, xx-cargo) -> Total duration: 12m 31s

Ok, did some testing locally, it does seem to download a bit less data.
It also makes the Dockerfile a bit less cluttered.

Same for this, lets wait after our next release before merging this one.
