The existing code relied on the Go build cache to avoid
needless work when obtaining the tailscale binaries.
For non-obvious reasons, the binaries were getting re-linked
every time, which added 600ms or so on my machine to every test.
Instead, build the binaries exactly once, on demand.
This reduces the time to run 'go test -count=5' from 34s to 10s
on my machine.

The VM test has two tailscaled instances running and interleaves the
logs. Without a prefix it is impossible to figure out what is going on.
It might be even better to include the [ABCD] node prefix here as well.
Unfortunately lots of interesting logs happen before tailscaled has a
node key, so it wouldn't be a replacement for a short ID.

By default httptest listens only on the loopback adapter.
Instead, listen on the IP the user asked for.
The VM test needs this, as it wants to start DERP and STUN
servers on the host that can be reached by guest VMs.

The DERPTestPort int meant two things before: which port to use, and
whether to disable TLS verification. Users would like to set the port
without disabling TLS, so break it into two options.

This adapts the existing in-process logcatcher from tstest/integration
into a public type and uses it on the side of testcontrol. This also
fixes a bug in the Alpine Linux OpenRC unit that makes every value in
`/etc/default/tailscaled` exported into tailscaled's environment, a-la
systemd [Service].EnviromentFile.

Previously this test would reach out to the public DERP servers in order
to help machines connect with eachother. This is not ideal given our
plans to run these tests completely disconnected from the internet. This
patch introduces an in-process DERP server running on its own randomly
assigned HTTP port.

Instead of pulling packages from pkgs.tailscale.com, we should use the
tailscale binaries that are local to this git commit. This exposes a bit
of the integration testing stack in order to copy the binaries
correctly.
This commit also bumps our version of github.com/pkg/sftp to the latest
commit.
If you run into trouble with yaml, be sure to check out the
commented-out alpine linux image complete with instructions on how to
use it.
