David Anderson 77354d4617 wgengine/magicsock: unblock wireguard-go's read on magicsock shutdown.
wireguard-go closes magicsock, and expects this to unblock reads
so that its internal goroutines can wind down. We were incorrectly
blocking the read indefinitey and breaking this contract.

David Anderson 643bf14653 wgengine/magicsock: disable the new ping test.
It's extremely flaky in several dimensions, as well as very slow.
It's making the CI completely red all the time without telling us
useful information.

Set RUN_CURSED_TESTS=1 to run locally.

David Anderson c8ebac2def wgengine/magicsock: try deflaking again.
This change just alters the semantics of the one flaky test, without
trying to speed up timeouts on the others. Empirically, speeding up
the timeouts causes _more_ flakes right now :(

David Anderson c5835c6ced wgengine/magicsock: temporarily deflake.
The remaining flake occurs due to a mysterious packet loss. This
doesn't affect normal tailscaled operations, so until I track down
where the loss occurs and fix it, the flaky test is going to be
lenient about packet loss (but not about whether the spray logic
worked).

David Anderson bd60a750e8 wgengine/magicsock: fix packet spraying test to (mostly) pass.
It previously passed incorrectly due to bugs. With those fixed,
it becomes flaky for 2 reasons. One of them is the wireguard handshake
race, which can eat the 1st sprayed packet and prevent roamAddr
discovery. This change fixes that failure, by spreading the test
traffic out enough that additional spraying occurs.
