        signal/ptrace: fix cgroup2/freezer long runtimes

        As reported in the thread: https://lkml.org/lkml/2019/10/1/789, in
        kernels with commit 76f969e8948d82 [cgroup: cgroup v2 freezer], we
        were seeing much longer runtime in strace/ptrace tests (4 minutes
        versus 4 seconds).

        The issue only manifests if CONFIG_PREEMPT is enabled, which is in
        all of the default configurations.

        As sugggested in the thread, the movement of preempt_enable_no_resched()
        until after the cgroup is frozen returns the behaviour to pre-5.2
        runtimes.

With this change in place, our times are back to normal:

   root@qemux86-64:~# cd /usr/lib/strace/ptest/tests
   root@qemux86-64:/usr/lib/strace/ptest/tests# time ../strace -o log -qq -esignal=none -e/clock ./printpath-umovestr>ttt

   real    0m3.909s
   user    0m0.534s
   sys     0m3.342s

This will eventually loop around via -stable, or may need future
tweaks, but it does address the immediate issue/symptom that we are
seeing, with no obvious side effects.
