On macOS, `mkdir("x/')` behaves differently than `mkdir("x")` if `x` is
a dangling symlink (the formed succeed while the latter fails). So make
sure we always strip the trailing slash.

This fixes the warning

When we're fetching by rev, that file doesn't necessarily exist, and we
don't care about it anyway.
The current backport action cannot automerge because
the github action bot does not trigger github CI actions.
Mergify instead does not have this limitation and can also
use a merge queue.
On top we have now a declarative configuration to allow
contributers to add new tests to required without having access
to the github org.
An example pull request and backport can be seen here:
https://github.com/Mic92/nix-1/pull/4
and here:
https://github.com/Mic92/nix-1/pull/5
To complete the setup the mergify app must be enabled for this repository.
It's already installed in the nixos organization for nixos-hardware and
other repositories.

Fixes
$ nix flake metadata --store /tmp/nix nixpkgs
error: path '/tmp/nix/nix/store/65xpqkz92d9j7k5ric4z8lzhiigxsfbg-source/flake.nix' is not in the Nix store
This has been broken since 598deb2b23.
downloadTarball() is used by `-I foo=<url>` etc. fetchToStore() needs
the accessor to have a fingerprint to enable caching.
Fixes#11271.

this should make it more obvious how things are related to each other, and also
hopefully expose the historical context without having to say on every
corner that these details are accounting for legacy decisions.
