Subject: [PATCH] Change default temp on Linux to /var/tmp.

Previously, the default temporary directory was /tmp on Linux and
/private/tmp on macOS. On many Linux distros, including at least Fedora,
/tmp is stored in RAM. This diverges from the behavior on macOS and has
led to bugs, most notably the inability to install large bottles on
memory-limited machines.
