Update to PoDoFo 0.9.8 (last <1 version)

From earlier last year, when upstream froze their tree to switch to a new
pdfmm code base with their 1.0.0 release: https://podofo.sourceforge.net/

Looks like this version fixes some CVEs:
https://sourceforge.net/p/podofo/code/commit_browser

Symbol removals and size changes as per check_sym, so bump major.

Tidy up the Makefile while here.
No PLIST change.
Builds fine, sysutils/krename still builds against the new version.
