This is weird. We're seeing some installs where formulae have no opt prefix and no linked keg record, *but* still ended up linked into the prefix. Upgrades will blow up in this case because the old symlinks won't get deleted and Homebrew will report a nonsensical error message about not being able to link over another link from the same formula! Since the optpath is either missing or pointing to the wrong destination at this point, the checks for conflict linking above will have failed. We should instead be safe to simply blow away these conflicting symlinks and replace them with the new targets. Fixes https://github.com/Homebrew/homebrew-core/issues/68866.
