bug#10688: The default mode for Perl should be cperl-mode instead of perl-mode

Let me put it some other way:

If/when someone is willing and able to take over maintenance of
cperl-mode (starting with cleaning up the Emacs-19-style-code-cruft),
then I might consider switching the default to cperl-mode.

But it might be easier to start from perl-mode and add cperl-mode chunks
to it.
