Ensure all store types support "real" URIs

Browse source 
In particular `local://<path>` and `unix://` (without any path) now
work, and mean the same things as `local` and `daemon`, respectively. We
thus now have the opportunity to desguar `local` and `daemon` early.

This will allow me to make a change to
https://github.com/NixOS/nix/pull/9839 requested during review to
desugar those earlier.

// The `parseURL` function supports both IPv6 URIs as defined in
// RFC2732, but also pure addresses. The latter one is needed here to
// connect to a remote store via SSH (it's possible to do e.g. `ssh root@::1`).
//
// This function now ensures that a usable connection string is available:
// * If the store to be opened is not an SSH store, nothing will be done.
// * If the URL looks like `root@[::1]` (which is allowed by the URL parser and probably
// needed to pass further flags), it
// will be transformed into `root@::1` for SSH (same for `[::1]` -> `::1`).
// * If the URL looks like `root@::1` it will be left as-is.
// * In any other case, the string will be left as-is.
