net-firewall/nftables-0.9.4-r2: revbump, cleanup deps, provide man pages

It turns out that flex and bison aren't actually needed to build, but
there was a bug in the build system that made it abort if they weren't
available. Add a patch to fix this bug, and remove the extra deps.

Disable USE=doc by default and provide pre-built man pages in a separate
tarball. Script to build them is at man-pages/gen-manpages.bash
