Subject: [PATCH] fix library doctest: not failing on some feature gates as
 expected

Updating the behavior of `fn is_unstable_reexport` to return false for bootstrap environment
would result in a breakage of #94972.
This was the quickest and simplest solution to fix this elusive bug, which was only identified
through miri tests.
