Remove usage of __file__ as backup file in import (#617)
Remove usage of __file__ as backup file in import (#617)

If a zip was imported without a 'binary' file, the submit manager would
use __file__ as a default, causing the target to be set to
<somepath>/submit.pyc. If delete_original is enabled, this would cause
Cuckoo to delete a Cuckoo file. The default file has now been replaced with an empty
tmp file.
