[PATCH] sockaddr_ntop(): kill warning on printf argument

[Vitezslav Samel]

gcc-4.7.0 on x86-64 spills out this warning:

src/sockaddr.c: In function "sockaddr_ntop":
src/sockaddr.c:131:4: warning: format "%u" expects argument of type
                      "unsigned int", but argument 3 has type
                      "size_t" [-Wformat]

Change the "%u" format to "%zu" (available since glibc-2.1) to prevent
this warning.
