[Libguestfs] [PATCH v8 02/42] mllib: Move Progress OCaml bindings to common/mlprogress.



The ‘Progress’ module is a self-contained library with the only
dependencies being:

 - the C ‘progress’ implementation

Move it to a separate ‘common/mlprogress’ directory.

This change is pure code refactoring.
