[regression] Bulding socket.c fails on Amazon Linux 2023 (and other OSs)

[gorloffslava]

Describe the bug

Looks like we've already had this bug before:

1. posix/socket: fix missing include #506
2. Int types #514

And looks like this commit reintroduces this issue: d04508d#diff-bbb6031b15894efd8c3b6ae10be38d407f72ac6c844513199348725cf044782c

It relies on that inttypes.h is included transitvely via net/if.h, which isn't the case on many OSs, including Amazon Linux 2023 amon others.

Expected Behavior

Compilation works

Current Behavior

Compilation fails with an error:
