create_cache(): new variable and argument changes

- If an argument is supplied to create_cache(), it will not create the default
  subdirectories (build/pkg/export).
- create_cache() now also globally sets the $tmp_dir variable, which is the
  default directory + $pid variable

Changes above do not affect the previous usage of the function, so it is not
considered a breaking change.
