Merge #1635

1635: Remove EventFlag::EV_SYSFLAG r=rtzoeller a=rtzoeller

It is not stable across OpenBSD versions and is reserved by the system on FreeBSD and NetBSD.

This should fix the nix build for OpenBSD, which is failing due to rust-lang/libc#2596. Bump the libc dependency to uptake that change.
