Tools: setup-unit: workarounded macOS tmp file permissions.

alejandro-colomar · alejandro-colomar · commit 2435bd1c3a55 · 2023-01-02T22:44:18.000+01:00
mktemp(1) in macOS uses a weird directory where only the running user
has permissions.  If we use that for the welcome website, unitd(8) won't
be able to read the page.  Use a directory at $HOME before trying a tmpdir.
