xfsprogs: Invoke bulkstat ioctl with XFS_BULK_IREQ_NREXT64 flag
This commit adds support to libfrog to enable reporting 64-bit extent counters
to its users. In order to do so, bulkstat ioctl is now invoked with the newly
introduced XFS_BULK_IREQ_NREXT64 flag if the underlying filesystem's geometry
supports 64-bit extent counters.
