testing/care: new aport
https://proot-me.github.io/care/ Comprehensive Archiver for Reproducible Execution
This one was a subpackage of testing/proot, but I've made it independent to make package manager show correct package version.
Caveat: new package has version 2.2, while package in repo has version 5.3.0 inherited from its origin package.
I specified @cpixl as a maintainer, so it would be good to have an approval from him.
Fixes #13488 (closed)
