Use /var/tmp for media cache path in apache/nginx configs

The /var/tmp directory is not mounted as tmpfs unlike /tmp which is
mounted as such on some distros like Fedora or Arch. Since there isn't
really a benefit to having the cache on tmpfs, this change should allow
for a larger cache if needed without worrying about running out of RAM.
