Bug#843561: certbot: Skip use perl in cron-script, just use shell

[Kazuhiro NISHIYAMA]

I think `$((RANDOM\%3600))` always means 0 when /bin/sh is dash.
I think it should be `bash -c 'sleep $((RANDOM\%3600))'` or something else.

[Hans Schou]

Package: certbot
Version: 0.9.3-1
Severity: wishlist

Dear Maintainer,

In /etc/cron.d/certbot perl is the only place used. It could be solved with
just shell evaluation and sleep. A more simple script.

-0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && 
perl -e 'sleep int(rand(3600))' && certbot -q renew
+0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && 
/bin/sleep $((RANDOM\%3600)) && certbot -q renew
