Make OCaml examples executable and objdumpable (#2853)

Changes:

- ocaml.default.properties:
  - add the relevant flags for execution and emitting binaries
  - add nicer version number reporting
  - let CE know `objdump` can be used on ocaml objects

- ocaml.js:
  - update optionsForFilter for both executable and object handling
  - override the getter for executable to work within ocamlopt context
