Makefile: use urfave_cli_no_docs for binaries that don't need it

Browse Source 
We only need the `ToMan()` as part of the `bin/gen-manpages` binary, which
generates the man-pages; other binaries don't use this code, so we can
set the `urfave_cli_no_docs` build-tag to exclude `cpuguy83/md2man` and
`russross/blackfriday` (and other dependencies) from the binaries:

Before:
