With the structured logging it makes more sense to tune this down a
bit. Also, this way it is consistent with Thomas Wood's new activity
indicator helper.

Spotted while discussing Thomas' patch with him.

v2: Thomas noticed that I've forgotten the fflush. Extract
igt_interactive_info for both igt_progress and igt_print_activity.

v3: Interactive output should go to stderr. Also extract the "is this
a terminal" check.

Not reusing the igt_warn() is great as well (we had earlier problems
when igt_warn* became smarter...)

Nothing to complain about here, lgtm.
