[DRE-maint] Bug#1102979: ruby3.1: depend on libcrypt-dev explicitly

[Helmut Grohne]

Source: ruby3.1
Version: 3.1.2-8.5
Tags: patch
User: helmutg at debian.org
Usertags: libcrypt-pkgconf

ruby3.1 uses libxcrypt during build, but it also exposes this header to 
its downstreams by including -lcrypt in its pkgconf .pc.  There is an 
effort[1] to drop libcrypt-dev from the build-essential package set. 
This will not happen during the trixie freeze, but some months into the 
forky cycle. Once dropped, ruby3.1 and reverse dependencies of 
ruby3.1-dev will fail to build from source.  While looking into it, I 
noticed that the .pc file also contains -lz without a matching 
dependency. I'm attaching a patch to make these dependencies explicit. 
It is safe for inclusion into trixie, but it does not warrant an upload 
of its own at this time of the freeze.
