If we understand it correctly, unpoision FILE would be only for inlined routines accessing FILE buffer(s) directly. On NetBSD we enforce _REENTRANT for all sanitizers in order to support only _REENTRANT variations of calls that go through libc calls.

There is however an exception with `*_unlocked` functions that are still inlined (putc_unlocked(), getc_unlocked(),...) and probably for them we still want to keep SANITIZER_HAS_STRUCT_FILE=1. Such interfaces are niche but still used according to https://codesearch.debian.net/

@vitalybuka @kcc @dvyukov @eugenis

Please help to make it clearer.
