Also tweak `pathAccessible` to ignore other relevant errors too. It was documented as ignoring permission errors but it was only ignoring `EPERM`, which comes from the darwin sandbox, and not ignoring `EACCESS` which is the real permission error. I figured it also makes sense to ignore `ELOOP`. Fixes: https://git.lix.systems/lix-project/lix/issues/560 Change-Id: Ibb849b68d07386eb80afb52b57f7d12b3a48a202
