Cleanup the generation of the nix3 manpages

Browse source 
Use a dedicated make target for the man page rather than bundling the
generation as part of `install`.
Also make sure that `make install` is a fixpoint by

- Removing the generated markdown files from `MANUAL_SRCS`
- Not having the manpage generation write in its source directory so as
  to not update its timestamp (it would run each time otherwise)
