Introduce SANITIZER_NETBSD in sanitizer_platform.h

[krytarowski]

Summary

Add defines for new NetBSD: SANITIZER_NETBSD,
it will be used across the codebase for sanitizers.

NetBSD is a POSIX-like platform, add it to SANITIZER_POSIX.

Part of the code inspired by the original work on libsanitizer in GCC 5.4 by Christos Zoulas.
