Mark ocaml_augeas_source w/o aug_source as noreturn

If aug_source is not available, the implementation of
ocaml_augeas_source just raises Failure: the caml_failwith function used
for that is marked as noreturn, and thus with more strict compiler flags
it can fail to build.

As solution, mark it as noreturn when aug_source is not available.
