This factors out some commonality in calling fromURL() and handling
the "dir" parameter into a fromParsedURL() helper function.

I'd messed up a rebase in my previous iteration, causing `weakly_canonical` to reappear,
but not trigger a test failure.
These two functions behave similarly when the argument is a path that points to a broken
symlink. `weakly_canonical` would not resolve it because the target doesn't exist, and
`makeParentCanonical` would not resolve it, because it never resolves the final path
element.
This new test case now also tests a valid symlink, "differentiating" the two.

Just now there is a dependency on cachix, which means we cannot test
the installer in CI if forks do not have the necessary secrets set up.
We replace this with a simple http server that serves the installer and
can be both used in CI and locally.

src/nix/flake.md describes the format of flake.lock files. Before this
change, it said that the original field was “The original input
specification from `flake.lock`[…]” The original input specification is
in flake.nix, not flake.lock.

Commit cfe66dbec updated `nix upgrade-nix` to use
`ExecutablePath::load().find`, which broke the logic for finding the
profile associated with the nix executable. The error looks something
like:
```
$ sudo -i nix upgrade-nix --debug
found Nix in '"/nix/store/46p1z0w9ad605kky62dr53z4h24k2a5r-nix-2.25.2/bin/nix"'
found profile '/nix/store/46p1z0w9ad605kky62dr53z4h24k2a5r-nix-2.25.2/bin'
error: directory '"/nix/store/46p1z0w9ad605kky62dr53z4h24k2a5r-nix-2.25.2/bin/nix"' does not appear to be part of a Nix profile
```
This seems to happen for two reasons:
1. The original PATH search resulted in a directory, but `find` returns
the path to the executable. Fixed by getting the path's parent.
2. The profile symlink cannot be found because
`ExecutablePath::load().find` canonicalizes the executable path. I
updated find to normalize the path instead, which seems more in line
with how other programs resolve paths. I'm not sure if this affects
other callers though.
I manually tested this on macOS and Linux, and it seemed to fix
upgrading from 2.25.2 to 2.25.3.

- This speeds up macOS builds from 30 minutes to 11 minutes (3x faster).
- Also improve error reporting e.g. printing out what actually failed to build.
- As a result we also no longer need swap.

Before this change, expressions like:
with import <nixpkgs> {};
runCommand "foo" {} ''
echo '@nix {}' >&$NIX_LOG_FD
''
would result in Lix crashing, because accessing nonexistent fields of
a JSON object throws an exception.
Rather than handling each field individually, we just catch JSON
exceptions wholesale. Since these log messages are an unusual
circumstance, log a warning when this happens.
Fixes#544.
