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 at qemux86-64:~# cd /usr/lib/strace/ptest/tests
root at 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.
