Delete some commented out code in cperl-mode.el

The differences between this and the existing `cperl-ps-print-init'
are that some faces had been moved from italic to bold or vice versa,
and that there were some obsolete or non-existent face names
mentioned.  So there is no point to keeping it given that it's been
commented out since 1999.

* lisp/progmodes/cperl-mode.el: Delete code commented out since 1999:
a slightly different, duplicate definition of `cperl-ps-print-init'.
