strerror() represents ETIMEDOUT a bit different in Linux and macOS /

As John and Thomas noted, the new iotests fails for FreeBSD and maxOS.
Here is a fix. Would be great if someone can test it.

I tried to push it by

   git push --force  -o ci.variable="QEMU_CI=1"

to my block branch, I get a blocked pipeline
   https://gitlab.com/vsementsov/qemu/-/pipelines/580573238
but it doesn't have neither freebsd nor macos jobs.. How to get them?

If we know for sure that it’s ETIMEDOUT, how about os.strerror(errno.ETIMEDOUT)?
