[3.13] gh-145548: Use VMADDR_CID_LOCAL in VSOCK socket tests (GH-145589)

[miss-islington]

Prefer VMADDR_CID_LOCAL instead of VMADDR_CID_ANY for bind() in the
server. Skip the test if bind() fails with EADDRNOTAVAIL.

Log vsock CID in test.pythoninfo.

• Issue: VSOCK test_socket.testStream() fails on aarch64 Fedora Stable 3.x buildbot #145548

[vstinner]

I will wait for Fedora Stable buildbots to pass on the main branch before merging the change to the 3.13 branch.
