command line, client-test: avoid "g_set_application_name not set" warning

When glib logging is invoked, it check the application name and complains
if not set:
** (process:10130): WARNING **: g_set_application_name not set.

With output redirection we hide this in the command line, but it
showed up in client-test when the system was in a state were another
glib WARNING was triggered.

This patch sets the unlocalized program name instead of using a
localized application name, because we don't have and don't need
localization for these two programs. That seems to satisfy glib.
