tests: Clarifies agnhost's entrypoint-tester's usage

Browse Source 
Some of the entrypoint-tester related tests overrides agnhost's default entrypoint
with agnhost-2, and this function's args will only contain the subcommand's
args (./agnhost entrypoint-tester these args), but we need to print *all* the
args, which is why os.Args should be printed instead.
