unix: add unexported name_to_handle_at and open_by_handle_at types & …

…wrappers No usable change for users in this CL; just auto-generated syscall wrapper funcs & types. The next CL will have hand-written code adding the nice Go API around these unexported symbols. (as outlined in the comment at https://golang.org/issue/30537#issuecomment-470284573) Updates golang/go#30537 Change-Id: I5e34df517efcf509fff97f670425500cc6608d59 Reviewed-on: https://go-review.googlesource.com/c/sys/+/172584 Run-TryBot: Brad Fitzpatrick <[email protected]> TryBot-Result: Gobot Gobot <[email protected]> Reviewed-by: Tobias Klauser <[email protected]>
