This adds a new temp-dir setting for controlling the temporary directory
without having to change the TMPDIR env var. This can be used to e.g.
use a path on a case-sensitive store on macOS for temporary files
without changing the TMPDIR var used by interactive shells or commands
invoked with `nix run`.
This also stops unsetting `TMPDIR` on darwin when the env var value
starts with `/var/folders/`, preferring instead to just do the check
when reading `TMPDIR`. This way the inherited `TMPDIR` env var is
preserved for child processes (such as interactive shells).
As a side effect this changes the behavior of `nix-build -o ''` to act
like `nix-build --no-out-link` instead of failing with an error caused
by trying to create a symlink at the cwd.

nix-buildnow treats --out-link ''
the same as --no-out-link. This matches
nix build behavior. Previously when building the default output it
would have resulted in throwing an error saying the current working directory already exists, and when building any
other output it would have resulted in a symlink starting with a hyphen such as -doc, which is a footgun for
terminal commands.
