btrfs-progs: Add new btrfs_open_ctree_flags CHUNK_ONLY
Add new flag CHUNK_ONLY and internal used only flag __RETURN_CHUNK.
CHUNK_ONLY will imply __RETURN_CHUNK, SUPPRESS_ERROR and PARTIAL, which
will allow the fs to be opened with only chunk tree OK.
This will improve the usability for btrfs-find-root.
