[coqdep] Remove support for `-c` ocamldep replacement.

There is not need for coqdep to ship an `ocamldep` replacement, in
particular:

- not used in the main build since a long time
- not tested
- not kept up to date with upstream

This allows for a significant reduction of `coqdep` code, including
some duplicated code from `ocamllibdep`.

`coq_makefile` now uses `ocamllibdep` to process `mllib/mlpack` files,
so it has then to be installed.

We also remove the residual `-slash` option.
