In continuation of early fileop credential changes, modify fo_ioctl() to

accept an 'active_cred' argument reflecting the credential of the thread
initiating the ioctl operation.

- Change fo_ioctl() to accept active_cred; change consumers of the
  fo_ioctl() interface to generally pass active_cred from td->td_ucred.
- In fifofs, initialize filetmp.f_cred to ap->a_cred so that the
  invocations of soo_ioctl() are provided access to the calling f_cred.
  Pass ap->a_td->td_ucred as the active_cred, but note that this is
  required because we don't yet distinguish file_cred and active_cred
  in invoking VOP's.
- Update kqueue_ioctl() for its new argument.
- Update pipe_ioctl() for its new argument, pass active_cred rather
  than td_ucred to MAC for authorization.
- Update soo_ioctl() for its new argument.
- Update vn_ioctl() for its new argument, use active_cred rather than
  td->td_ucred to authorize VOP_IOCTL() and the associated VOP_GETATTR().
