Hauke Mehrtens f75c726430 dropbear: backport some security fixes from 2026.90
This cherry picks the following changes:

- Security: server: Fix ability to bypass an authorized_keys "forced_command"
  option by an authenticated user, if Dropbear is running with "-t" option.
  ("-t" is require both password and public key).

- Security: server: Open authorized_keys non-blocking. This avoids getting stuck
  with special files, could allow denial of service from local users.

- Security: scp: Add missed patch to fix CVE-2019-6111 allowing a malicious server
  to overwrite unexpected files.
  143291baca
  Patch from OpenSSH, reported missing by Asim Viladi Oglu Manizada @manizada

  Note breaking change: "-r" is now disallowed when the target directory exists
  (an additional change in Dropbear's version). If that's required an alternative
  such as rsync could be used.

- Security: scp: Clear setuid/setgid bits on received files.
  443ccc1fd1
  Patch from OpenSSH, tracked as CVE-2026-35385

- Security: client/server: Fix close() of a file descriptor from an out-of-bounds
  read. This seems difficult to exploit but may have unforeseen effects.
