File patch6_7.diff of Package libtirpc.openSUSE_Leap_42.3_Update

Most folks seem to copy this gentoo patch to silence an alleged
_FORTIFY_SOURCE=2 warning:
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/net-libs/libtirpc/files/libtirpc-0.2.1-fortify.patch?diff_format=s&revision=1.2&view=markup

Given that gethostbyname is obsolescent, let's just use getaddrinfo
instead (to silence warnings about the OB function).

I am undecided if setting AI_V4MAPPED and AI_ADDRCONFIG is a good idea.
Personally i would be inclined to s/if 0/if 1/ but i'll leave that up to
you.
