pageinspect: Use better macros to get special page area for GIN and GiST 

These five code paths are the last ones that made use of
PageGetSpecialPointer() to get the special area of such pages, while
those index AMs have already macros to do this job.

Noticed while reviewing the use PageGetSpecialPointer() in the whole
tree, in relation to the recent commit d16773c.
