userland: Fix POSIX compliance expectation

We have errors like below with glibc 2.22+

net_sockets_common.c:139:20: error: storage size of 'hints' isn't known
    struct addrinfo hints, *info, *p;
                        ^

newer glibc has now fixed the definitions of getaddrinfo and ilk to be
enabled with correct posix version.

+Subject: [PATCH] Use newer POSIX macro
+
+Define _POSIX_C_SOURCE such that it demands correct
+posix interfaces, netdb.h declares interfaces such as
+getaddrinfo if __USE_POSIX, i.e. POSIX.1:1990 or later.
+However, these interfaces were new in the 2001 edition of POSIX
+therefore ask for Extension from POSIX.1:2001 since we use addrinfo
+structure here.
