[9fans] ape: getsockname: wrong byte order in sin_port

[Yaroslav]

APE's getsockname() returns port with bytes swapped (on 386).
Fix:

/n/dump/2013/0108/sys/src/ape/lib/bsd/_sock_ingetaddr.c:35,41 -
/sys/src/ape/lib/bsd/_sock_ingetaddr.c:35,41
  if(p){
  *p++ = 0;
  ip->sin_family = AF_INET;
- ip->sin_port = atoi(p);
+ ip->sin_port = htons(atoi(p));
  ip->sin_addr.s_addr = inet_addr(name);
  if(alen)
  *alen = sizeof(struct sockaddr_in);

Python needs to be relinked.
