Emoji: Remove extraneous sprintf() from _print_emoji_detection_script().

The `sprintf()` is not being passed any values, and there is no placeholder to replace.
This originated in r52132 in which I erroneously included this `sprintf()` in
two places. I fixed one of the cases in r52151 but I missed the other.

Follow-up to [52132], [52151].

Fixes #58436.
See #44632.
