base-system-3: gnupg construye — gpg 2.4.9 (firma/cifrado), cierra la cadena crypto

b3:f9de6d2a. deps = cadena canónica sellada (libgpg-error/libgcrypt/libassuan/libksba/npth/zlib).
Fase configure explícita --disable-{tofu,scdaemon,dirmngr,doc,bzip2} + --with-*-prefix=/usr. gpg+gpgv
estáticos; round-trip cifrado simétrico -c/-d + --print-md SHA512 verificados. Nota: NO apareció el
ubsan de libz.a (el zlib limpio de este mismo commit-set ya se materializa). base-system-3 completo.
