Add host.id for non-containerized systems

[matt-hensley]

Fixes #1263

Only mocked the file system for Linux.

BSD, MacOS, and Windows all shell out to get the ID. I've added tests covering parsing the output on MacOS and Windows.

Any and all feedback is welcome, I haven't written PHP in a long time.

Done! Thanks, @matt-hensley
