  sanitizer_common: tighten on_print hook test

The new tsan runtime does not support arbitrary forms
of recursing into the runtime from hooks.
Disable instrumentation of the hook and use write instead
of fwrite (calls malloc internally).
The new version still recurses (write is intercepted),
but does not fail now (the issue at hand was malloc).

Depends on D112601.
