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.
