[Buildroot] [PATCH 1/2] zeromq: bump to version 4.1.3

[Gustavo Zacarias]

Add upstream patch to fix build failure of zeromq with latest
libsodium, since sodium_init() has a retval and is now declared to warn
on unused result, with zeromq treating warnings as errors.

+Subject: [PATCH] Problem: return code of sodium_init() is not checked.
+
+There are two todo comments in curve_client.cpp and curve_server.cpp that suggest
+checking the return code of sodium_init() call. sodium_init() returns -1 on error,
+0 on success and 1 if it has been called before and is already initalized:
