Description of problem:
/etc/cron.daily/rkhunter fails on fresh installs as it tried to create a file in
a non-existant directory.  It tries to create a temp file in /var/rkhunter/tmp,
however that directory does not exist on fresh installs.  This is not a problem
for users who upgrade from older versions, as that directory will exist from
their old package.
