qcow2-bitmap: initialize bitmap directory alignment

Browse Source 
Valgrind detects multiple issues in QEMU iotests when the memory is
used without being initialized. Valgrind may dump lots of unnecessary
reports what makes the memory issue analysis harder. Particularly,
that is true for the aligned bitmap directory and can be seen while
running the iotest #169. Padding the aligned space with zeros eases
the pain.
