[PATCH 3/4] gnulib-tool: abort loops early where possible.

[Ralf Wildenhues]

* gnulib-tool (func_modules_add_dummy, func_emit_lib_Makefile_am)
(func_emit_tests_Makefile_am, func_import): Abort loops early if
we already know the answer.

Sorry, I forgot a couple of instances.  Updated patch.

Cheers,
Ralf
