Use posix_memalign() for memory used to write bitmaps

This makes super[01].c properly align buffers used for the bitmap
using posix_memalign() to make sure the writes don't fail in case the
bitmap is opened using O_DIRECT.

This is based on https://bugzilla.redhat.com/show_bug.cgi?id=789898
and an initial patch by Alexander Murashkin.
