GLib uses ~/.cache as a fallback for g_get_user_runtime_dir() if
XDG_RUNTIME_DIR isn't set.

XDG_RUNTIME_DIR is typically only set on Linux systems that have a
correctly-set-up systemd-logind and pam_systemd, or on Unixish systems
that have some other implementation of XDG_RUNTIME_DIR such as Canonical's
<https://launchpad.net/pam-xdg-support> (which was present in some older
Ubuntu releases, but was abandoned after they adopted systemd-logind).
