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

elfutils has historically shipped 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, that subpackage 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).

gdb is a special case: `dnf repoquery --whatdepends default-yama-scope`
shows gdb-headless (not the main gdb subpackage) as the declared
consumer today. The FESCo proposal explicitly excludes gdb-headless
and gdb-minimal from the new Recommends, since their consumers
(ABRT, rpmbuild) don't need non-child ptrace. The Recommends belongs
on the user-facing gdb subpackage instead.

Please make two changes on rawhide:

1. Remove from gdb-headless (and gdb-minimal, if it has it):
  Recommends: default-yama-scope

2. Add to the main user-facing gdb subpackage:
  Recommends: yama-ptrace-enable
