Homebrew packages can't be asserted via the `host.package` module on Linux

[coaxial]

Would it be possible to make it work for Linux too? It only works for macOS at the moment.

As an alternative if this helps anyone, I am doing this:

# host.package doesn't work with homebrew packages on Linux
def test_homebrew_packages(host):
    packages = {
        'git-delta': re.compile(r'delta \d+\.\d+\.\d+', re.M),
        'hub': re.compile(r'hub version .*', re.M),
    }

    for package, version_re in packages.items():
        version = host.run("bash -l -c " + package + " --version").stdout

        assert version_re.match(version)

Not as robust as using the package module but better than nothing.
