From the machines tab its hard to differenciate desktop Linux installs from
server Linux installs. Transmitting this information should make this
determination a lot easier.
Due to the reality that tailscaled is likely a system process, the standard
checks based on XDG_SESSION_TYPE or DISPLAY environment variables are not
possible (those variables won't be set). Instead, we look for listening
unix sockets that are typical of desktop installs.

The MSI installer sets a special sentinel value that we can use to detect it.
I also removed the code that bails out when the installation path is not
`Program Files`, as both the NSIS and MSI installers permit the user to install
to a different path.

We replace the cmd.exe invocation with RtlGetNtVersionNumbers for the first
three fields. On Windows 10+, we query for the fourth field which is available
via the registry.
The fourth field is not really documented anywhere; Firefox has been querying
it successfully since Windows 10 was released, so we can be pretty confident in
its longevity at this point.

Turns out the iOS client has been only sending the OS version it first
started at. This whole hostinfo-via-prefs mechanism was never a good idea.
Start removing it.

With netns handling localhost now, existing tests no longer
need special handling. The tests set up their connections to
localhost, and the connections work without fuss.
Remove the special handling for tests.
Also remove the hostinfo.TestCase support, since this was
the only use of it. It can be added back later if really
needed, but it would be better to try to make tests work
without special cases.

Several other AWS services like App Run and Lightsail Containers
appear to be layers atop Fargate, to the point that we cannot easily
tell them apart from within the container. Contacting the metadata
service would distinguish them, but doing that from inside tailscaled
seems uncalled for. Just report them as Fargate.

Treat automated tests as their own, unique environment
rather than the type of container they are running in.
