Rely on /var/tmp, instead of /tmp, to store temporary data

The /var/tmp directory is made available for programs that require
temporary files or directories that are preserved between system
reboots. Therefore, data stored in /var/tmp is more persistent than data
in /tmp.

Files and directories located in /var/tmp must not be deleted when the
system is booted. Although data stored in /var/tmp is typically deleted
in a site-specific manner, it is recommended that deletions occur at a
less frequent interval than /tmp.

This change should prevent noisy diffs which occurred regularly after a
machine reboot.
