Note that it applies unpoison to all users of sys_fill_exact. It's redundant in some cases (e.g. when we read from /dev/urandom), but AFAIK it has no negative consequences (outside of outlandish scenarios of misbehaving libc), while allowing to simplify the code a fair bit.

We could move imports of errno_location for 4 targets which use this backends here, but I don't think it's worth the trouble since all 4 targets use different names.
