sys-fs/e2fsprogs: disable metadata_csum_seed and orphan_file features for new fs by default

This keeps support for metadata_csum_seed and orphan_file but doesn't *enable*
it by default in new filesystems.

Unfortunately, support was added in the same e2fsprogs release which enabled
it by default. By changing the defaults as Debian has, we give people a chance
to upgrade their initramfses, live media, etc, so they can actually mount partitions
created by such a new e2fsprogs.

It feels wrong to have to do this but I don't see much other choice. At least we're
in good company.

+Description: Disable metadata_csum_seed and orphan_file by default for Debian
+ .
+ There are a lot of debian packages that assume that mkfs.ext4 for
+ Debian N will work on Debian N-1 (and sometimes N-2, N-3, etc.).  This
+ is a bad assumption, but it's too late to fix this for Debian
+ Bookworm.
+ .
+ So revert making these feature a default for now.  We will enable it
+ again post Bookworm.
