APPS: Modify 'fipsinstall' to output all notifications on stderr
APPS: Modify 'fipsinstall' to output all notifications on stderr

The actual output of the 'fipsinstall' is the config file it outputs.
It should be possible to output that to standard output, and diverse
notification messages shouldn't be mixed in.  Therefore, we output
them to standard error instead.
