[PATCH] ext4/306: require 64bit feature to run ext4/306

[Xiao Yang <yangx.jy@cn.fujitsu.com>]

The 64bit feature isn't supported by mkfs.ext4 on RHEL6, so
we add _require_ext4_mkfs_64bit to check it.  If 64bit feature
isn't supported, we could skip this case.  This feature has
been produced by 'commit 02d6f47e9647d ("mke2fs: Fix up mke2fs
to be able to make 64-bit file systems")'.
