base-system: bash construye — shell real (GNU bash 5.3 estático)

b3:a03c1ad5. Arreglé el tarball (URL con vars abuild sin expandir → bash-5.3.tar.gz

(link estático) y las líneas install de bashrc/profile inexistentes. deps: ncurses+readline
+linux-headers. Primer shell POSIX completo del userland (hasta ahora sólo busybox sh).
