package/start-stop-daemon: fix build issues with musl and GCC 14

Unlike glibc and uClibc, musl doesn't play tricks with transparent
unions for the second argument to bind() to accept the various sockaddr
variants, but rather just defines it as "struct sockaddr*". As GCC 14 no
longer allows arbitrary implicit pointer casts, this results in a build
error. Import the upstream patch that adds the cast.
