LU-16879 mke2fs: disable metadata_csum_seed/orphan_file

Disable the new metadata_csum_seed and orphan_file features in
/etc/mke2fs.conf by default, otherwise some older kernels cannot
mount ext4 filesystems formatted with these options.

Also disable metadata_csum by default, since Lustre MDTs do not
work with this option (it conflicts with dir_data), and it's
not considered totally stable before kernel 3.18.

Fixes: fe341d59e ("mke2fs.conf: enable the metadata_csum_seed and orphan_file features by default")
