test.sh: use pikepdf instead of grep to check PDF

Browse source 
- no requirement on layout chosen by PDF engine anymore, thus we can
   test any pdf writer with this
 - check value at full path instead of anywhere in the document, thus no
   possible false positives if expected value was present in a different
   object
 - allows adding additional checks where we couldn't use grep before
   (multipage pdf created by pdfseparate)
