Brad Fitzpatrick 7d9b1de3aa netcheck,portmapper,magicsock: ignore some UDP write errors on Linux

Treat UDP send EPERM errors as a lost UDP packet, not something super
fatal. That's just the Linux firewall preventing it from going out.

And add a leaf package net/neterror for that (and future) policy that
all three packages can share, with tests.

Updates #3619
