test: add os-targeted integration tests

[reubeno]

For increased integration coverage, add new jobs that take the produced Linux/x86_64 release binaries and use them to run our compatibility and completion integration tests on each of Fedora, Debian, and Arch Linux.

In the future, we'll want to enable interactive tests and evaluate which other target platforms are appropriate for additional testing.
