cookbook: Strip leading and trailing space inside programlisting

It's a XSL FAQ to be able to chomp text nodes and we just have to copy
and paste a XSLT 1.0 solution from:
  http://dpawson.co.uk/xsl/sect2/N8321.html#d11325e833

Let's then empower our cookbook customization layer to chomp text nodes,
children of programlisting.
