Request packaging change for the ltrace side of FESCo Change
"Restrict ptrace by default" (fesco#3569, tracker rhbz#2448388).

elfutils ships a subpackage elfutils-default-yama-scope
whose sysctl file sets kernel.yama.ptrace_scope=0, disabling
yama's non-child ptrace restrictions. Because elfutils-libs
hard-Required it and is pulled in transitively by systemd, every
Fedora system has run with yama disabled.

Starting with Fedora 45 elfutils-0.195-1, elfutils-default-yama-scope
is renamed to yama-ptrace-enable, the hard Requires on elfutils-libs
is dropped, and the sysctl is installed only on systems where a
debugger-type package explicitly pulls it in. Systems without such
a package will fall back to the kernel default (ptrace_scope=1, child-only).
                                                                    
Please add the following to the relevant spec file for fedora >= 45:

  Recommends: yama-ptrace-enable

Recommends (not Requires) lets hardened environments opt out.
