Brad Fitzpatrick ef15096a7d control/controlclient, version/distro: detect NixOS explicitly
The fallthrough happened to work in controlclient already due to the
/etc/os-release PRETTY_NAME default, but make it explicit so it
doesn't look like an accident.

Also add it to version/distro, even though nothing needs it yet.

Brad Fitzpatrick 6298018704 control/controlclient: print disco keys NetworkMap diffs (debug change only)
NetworkMap text diffs being empty were currently used to short-circuit
calling magicsock's SetNetworkMap (via Engine.SetNetworkMap), but that
went away in c7582dc2 (0.100.0-230)

Prior to c7582dc2 (notably, in 0.100.0-225 and below, down to
0.100.0), a change in only disco key (as when a node restarts) but
without endpoint changes (as would happen for a client not behind a
NAT with random ports) could result in a "netmap diff: (none)" being
printed, as well as Engine.SetNetworkMap being skipped, leading to
broken discovery endpoints.

c7582dc2 fixed the Engine.SetNetworkMap skippage.

This change fixes the "netmap diff: (none)" print so we'll actually see when a peer
restarts with identical endpoints but a new discovery key.

Brad Fitzpatrick 05a79d79ae control/controlclient: rewrite, test NetworkMap.ConciseDiffFrom
It stood out a lot in hello.ipn.dev's profiles for generating a lot of
garbage (and thus GC CPU).

Brad Fitzpatrick b8edb7a5e9 control/controlclient: add Debug field to NetworkMap
As part of disabling background STUN packets when idle, we want an
emergency override switch to turn it back on, in case it interacts
poorly in the wild. We'll send that via control, but we'll want to
plumb it down to magicsock via NetworkMap.
