This reverts commit 43e82c9446, reversing
changes made to d79b9bdec0.
Since /proc/homeless-shelter returns a different errno than /homeless-shelter (ENOENT vs EACCES), we need to revert this change.
Software depends on this error code i.e. cargo and therefore breaks.
Incorrectly high expectations lead to frustration for users who
stick around to experience how useless it is for e.g. a devShell

Since we have a componentized build, we've solved the duplication.
In the new situation, building both with and without unit tests
isn't any slow than just a build with unit tests, so there's no
point in using the unit-tested build anymore.
By using the otherwise untested build, we reduce the minimum build
time towards the NixOS test, at no cost.
If you want to run all tests, build all attributes.
* add cross-references to `nix-path` overriding
while this information is already present in the settings, it's more
likely to be first accessed through the "lookup path" page, which
currently requires following two links to get to the practically
important bits.

This is because with the split packages of the Meson build, we simply
have no idea what directory the binaries will be installed in when we
build the library.
In the process of doing so, consolidate and make more sophisticated the
logic to cope with a few corner cases (e.g. `NIX_BIN_DIR` exists, but no
binaries are inside it).

* docs: unify documentation on search paths
- put all the information on search path semantics into `builtins.findFile`
- put all the information on determining the value of `builtins.nixPath` into the
`nix-path` setting
maybe `builtins.nixPath` is a better place for this, but those bits
can still be moved around now that it's all next to each other.
- link to the syntax page for lookup paths from all places that are
concerned with it
- add or clarify examples
- add a test verifying a claim from documentation
We should use a metric that weighs the related issues.
Counterbalancing time doesn't make much sense to me.
If it's around for longer, the fix will be relevant to more people.
