Zygo Blaxell 180bb60cde fs: add support and workarounds for btrfs fs_info v2 ...

Define a local copy of the header that has fields for the csum type
and length, so we can build in places that haven't caught up to kernel
5.5 headers yet.

The reason why the csum type and length are not unconditionally filled
in eludes me.  csum_length is necessarily non-zero, and the cost of
the conditional is worse than the cost of the copy, so the whole flags
dance is a WTF...but it's part of the kernel API now, so it's too late
to NAK it.
