[build] Remove coqmktop in favor of ocamlfind.

We remove coqmktop in favor of a couple of simple makefile rules using
ocamlfind. In order to do that, we introduce a new top-level file that
calls the coqtop main entry.

This is very convenient in order to use other builds systems such as
`ocamlbuild` or `jbuilder`.

An additional consideration is that we must perform a side-effect on
init depending on whether we have an OCaml toplevel available [byte]
or not. We do that by using two different object files, one for the
bytecode version other for the native one, but we may want to review
our choice.

We also perform some smaller cleanups taking profit from ocamlfind.
