fuse: optional supplementary group in create requests
Permission to create an object (create, mkdir, symlink, mknod) needs to
take supplementary groups into account.
Add a supplementary group request extension. This can contain an arbitrary
number of group IDs and can be added to any request. This extension is not
added to any request by default.
Add FUSE_CREATE_SUPP_GROUP init flag to enable supplementary group info in
creation requests. This adds just a single supplementary group that
matches the parent group in the case described above. In other cases the
extension is not added.
