package/nftables: do not build docs

Building docs requires dblatex with a working Jade Wrapper (jw) which may well be missing on the build machine, and we do not build our own.

Since docs are anyway removed from the target, just do not build them.

Tell ./configure that we do not have the required tools:
- DBLATEX=no to disable PDF generation
- DOCBOOK2X_MAN=no, DOCBOOK2MAN=no and DB2X_DOCBOOK2MAN=no to disable manpage generation

---
Changes v1 -> v2:
- do not touch Makefile.am, do not autoreconf, just pre-seed appropriate variables so ./configure concludes it does not have the required tools (Thomas)
