generate-man.sh: Only build md2man if it's not installed 

Distributions uses generate-man.sh to create man pages, however it only
assumes a container environment and attempts to build binaries towards
`/go` which might be an illegal path in `fakeroot`.

This patch ensures we only build `md2man` from the vendored sources if
the command is not present. This allows distributions to supply thier
packaged `md2man`.
