genext2fs: remove it

Remove genext2fs since we don't use it anymore, it can't support
ext4 well, either. We have used "mke2fs -d" to instead of it.

-Subject: [PATCH 12/19] Add rev 1 support, large file support, and rework holes
-
-Add support for individual files larger than 2GB, which requires some
-rev 1 filesystem support.
-
-Also, since we have a non-overly filesystem structure, rework the
-OP_HOLES hack and just put that flag in the filesystem structure.
-This avoid having to mess around with the reserved bytes (which
-changed with rev 1 support).
