[PATCH] debugfs: open with EXT2_FLAG_64BITS

[Eric Sandeen <sandeen@redhat.com>]

Pointing debugfs from the pu branch at a large filesystem is
still failing with:

 Filesystem too large to use legacy bitmaps while reading block bitmap

We need to open with EXT2_FLAG_64BITS; I'm not sure if this
should be a switch based on the size of the fs or not?

But in any case the below gets things moving enough to
use debugfs on a large filesystem.
