Improve apt.test_provides unit test

The unit test was failing on recent versions of Debian and Ubuntu
because the `login` package is no longer installing the binary on
`/bin/login` but rather on `/usr/bin/login`.

We have added a function which will retrieve the binary path depending
on the distro as well.

Resolves: #6028
