ec2 inventory plugin: fix whitespace around connection validity test

add_host should not be a changed action

The action doesn't actually change anything on a system, so setting
the status to changed is wrong. add_host is much like set_fact in that
regard.

Since changed is False by default, there is no need to explicity set
it, so just create an empty dict for result and add to it from there.

rhn_register - Correctly load up2date configuration

Previously, a configuration file name of None was being passed into
up2dateInitConfig().  This resulted in a correct configuration import,
but failed to properly save the configuration back to disk in the event
a different serverURL was supplied.  This change removes support for
customizing the up2date filename entirely, and relies on up2date to
choose the default config filename.
