[PATCH v1] tools: use integer division in convert-legacy-stream

[Olaf Hering <olaf@xxxxxxxxx>]

A single slash gives a float, a double slash gives an int.

    bitmap = unpack_exact("Q" * ((max_id/64) + 1))
TypeError: can't multiply sequence by non-int of type 'float'

This is broken for unknown reasons since 4.14.
