[Buildroot] [PATCH 1/1] package/dropbear: security bump version to 2026.92

[Bernd Kuhls]

https://matt.ucc.asn.au/dropbear/CHANGES

- Security: server: Don't allow -B (accept blank password) with
  -t (two factor auth). If run with -t and -B a user configured with a
  blank password would be allowed to log in without pubkey auth.
  https://github.com/mkj/dropbear/commit/23ec78285639edf068d86bb96f91cba755039740
  Reported by nvidia

- Security: server: Fix parsing of long authorized_keys lines.
  The remainder of a long line would be handled as the start of a new line.
  In the case where external programs add semi-trusted public keys to
  authorized_keys, a crafted key might bypass restrictions such as "command=".
