LU-11923 utils: fix mkfs.lustre meta_bg handling

If meta_bg is specified as a formatting option, mke2fs reports an
error because it conflicts with the default resize_inode feature,
which is enabled by default for filesystems under 2^32 blocks.

Enable meta_bg by default if the filesystem is over 2^36 blocks
(256TiB) or the group descriptor table grows too large.

Disable the resize_inode feature if meta_bg is explicitly specified
or if the filesystem is over 2^32 blocks.

Fix is_e2fsprogs_feature_supp() to return a boolean in the proper
sense for the function, rather than a 0 or -ve error number, since
that doesn't make sense for the name of the function.

Drop a level of indent in ldiskfs_make_lustre() by returning an
error directly if the ldd_mount_type is unknown.
