db: allow caching packages on tmpfs 

fixes #5616

The original intention was not use unnecessary space on tmpfs
e.g. if the cache directory is a mount point, but accidentally
left unmounted. But there are valid cases when packages are
intentionally wanted to be cached on tmpfs. If caching is not
desired, the user can just remove the cache directory.
