[Buildroot] [PATCH] package/sslh: add upstream patch to fix build w/ gcc-15

[Peter Korsgaard]

Add an upstream patch to fix a build issue related to struct
sockaddr_storage:

udp-listener.c: In function 'cnx_cmp':
udp-listener.c:39:30: error: initialization of 'struct sockaddr *' from incompatible pointer type 'struct sockaddr_storage *' [-Wincompatible-pointer-types]
   39 |     struct sockaddr* addr1 = &cnx1->client_addr;
      |                              ^
udp-listener.c:42:30: error: initialization of 'struct sockaddr *' from incompatible pointer type 'struct sockaddr_storage *' [-Wincompatible-pointer-types]
   42 |     struct sockaddr* addr2 = &cnx2->client_addr;
      |                              ^
udp-listener.c: In function 'hash_make_key':
udp-listener.c:55:29: error: initialization of 'struct sockaddr *' from incompatible pointer type 'struct sockaddr_storage *' [-Wincompatible-pointer-types]
   55 |     struct sockaddr* addr = &new->client_addr;
      |                             ^
udp-listener.c: In function 'udp_s2c_forward':
udp-listener.c:330:18: error: passing argument 5 of 'sendto' from incompatible pointer type [-Wincompatible-pointer-types]
  330 |                  &cnx->client_addr, cnx->addrlen);
      |                  ^~~~~~~~~~~~~~~~~
      |                  |
      |                  struct sockaddr_storage *
