clamav: fix unit test race condition

- fixed.

Wenn die unit tests laufen, versucht
   `clamav-0.104.2-0/source/unit_tests/input/xor_testfile.py`
den Folder `"build/unit_tests/input/clamav_hdb_scanfiles"` zu erstellen, der aber schon existiert.

im xor_testfile.py:55 wir erst ein mkdir(), dann ein open/write/close gemacht, innerhalb eines try:-blocks
