pylorax: Fix mksparse ftruncate size handling

Browse Source 
Make sure that os.ftruncate() is called with an int() size. Before python
3.10 it used to handle this internally, but in 3.9 it was deprecated and
in 3.10 it now raises an error:

    TypeError: 'float' object cannot be interpreted as an integer

This makes sure that the size is truncated to an int(). The value is in
bytes, so truncation does not lose anything.
