misc/html2ps: hardcode answers to the install script

If libwww-perl happens to be installed, one of the questions is
skipped, which throws everything out of sync and makes the
installation fail.

+-This is the installation script for html2ps. To get full functionality, some
+-external program packages need to be installed. You may wish to install these
+-first (see the enclosed documentation for addresses):
+-
+- * For conversion on inline images, any of the packages ImageMagick, pbmplus
+-   or netpbm.
+-
+- * To retrieve remote documents you must have libwww-perl. Alternatively,
+-   some program like wget or lynx.
+-
+- * To be able to generate cross references and DSC PostScript, you must
+-   have Ghostscript installed.
+-
+- * To be able to convert documents using the MATH element from HTML 3.0,
+-   you need both TeX and dvips.
+-
+-This script creates a file describing the local configuration. To make this
+-accurate, you should have your search PATH set to include the directories
+-where the abovementioned packages are. You must also have write access to
+-the directories where the files should be placed.
