introduced in 2.6.28, so we use accept4 everywhere. Unfortunately,
it turns out that the accept4 system call was only added to
linux-arm in 2.6.36, so for linux-arm only we need to try the accept4
system call and then fall back to accept if it doesn't work.

The code we use on linux-arm is the code we used in Go 1.17.
On non-arm platforms we continue using the simpler code introduced
in Go 1.18.

Adding accept4 to the ARM Linux kernel was:

Fixes #57333
