Bernd Schubert 5303265a48 coccicheck: Allow to show the executed command line
On my system one of the tests failed with
"Fatal error: exception Failure("No OCaml compiler found! Install either ocamlopt or ocamlopt.opt")".

Investigating such issues is easier if the executed command line is
being shown.
