media key: use the new function normalize_fpr (not for 2.x)

Browse Source 
It is important to keep this commit separated because the new function does not
exist on Engine 2.x; in case I need to backport bug fixes I need to avoid this.

Fix the media key test suite as well; now that FPRs are actually validated and
normalised I can no longer abuse media key functions passing intuitive
funny-looking FPRs.
