Per AGENTS.md 'DO NOT edit files under mainline recipes/ directly', create
a Red Bear fork under local/recipes/net/openssh/ that the build system
materializes via apply-patches.sh symlink.
Replaces two upstream placeholders:
1. The 'sed -i AddressFamily inet' workaround with a real capability
detection that probes relibc's <netinet/in.h> for AF_INET6 and
selects AddressFamily=any (dual-stack) or inet (IPv4-only)
accordingly. The OPENSSH_FORCE_IPV4=1 environment variable
overrides the probe to force IPv4-only.
2. The commented-out '# ssh-keygen -t ... -N ""' TODO with a real
subshell-rendered postscript that generates ed25519, rsa, and
ecdsa host keys (idempotent re-runs skip existing keys).
The patch list in the fork recipe is identical to the mainline
(just 'redox.patch' — the upstream-tracked Redox port). The Red Bear
modifications to the build are entirely in 'script =' below, so
no additional Red Bear overlay patch file is required.
Also extends local/scripts/apply-patches.sh with the 'net/openssh'
symlink entry under a new '# Network fork recipes' section.
