iproute2: fixes to compile on some systems.

1. Put the declarations of strlcpy and strlcat inside
   an #ifdef NEED_STRLCPY. Their declarations were already in a
   similar #ifdef.
2. In bpf_scm.h, include sys/un.h for struct sockaddr_un.
3. In utils.h, include time.h for struct timeval.

Tested: builds on ubuntu 14.04 with "make clean distclean; ./configure && make -j64"
Tested: 4.14.1 builds on Android with Android-specific #ifndefs for missing library code
