  Unescaped left brace in regex is deprecated

Bug description:
  [Impact]

   * Perl version in Artful complains about deprecated regex usage in 
     spamassassin. This works but floods consoles and status mails.

   * Fix is a backport of the small upstream change

  [Test Case]

   * simply run sa-learn in any way, for example
       $ sa-learn --help
     In unfixed versions you'll see the following all over the place (also 
     on install and in status mails)

       Unescaped left brace in regex is deprecated here (and will be fatal 
       in Perl 5.30), passed through in regex; marked by <-- HERE in m/^(.{ 
       <-- HERE ,200}).*$/ at 
       /usr/share/perl5/Mail/SpamAssassin/PerMsgStatus.pm line 923.

   * these should allow someone who is not familiar with the affected
     package to reproduce the bug and verify that the updated package fixes
     the problem.

  [Regression Potential]

   * sa-learn worked in some tests, but there could be unexpected 
     cases where this breaks by very slight behavior changes.
     OTOH the change is upstream a while now, so the chance it
     really broke anything is low.
     Also the change is essentially 1 chomp moved and 3 pattern matches 
     adapted to new syntax - so the amount that slips our review thoughts 
     should be low.

  [Other Info]
   
   * n/a
