hwdb/keyboard: fix match for for X+ Piccolo, again

I got infos from product_name:

$ cat /sys/class/dmi/id/product_name
X+ Piccolo

Turns out the modalias has a little difference:

$ cat /sys/class/dmi/id/modalias
dmi:bvnAmericanMegatrendsInternational,LLC.:bvr5.27:bd09/10/2025:br5.27:svnX-Plus.tech:pnX+Piccolo:pvrDefaultstring:rvnX-Plus:rnXPLUS-SERIES81x-DEV:rvrDefaultstring:cvnDefaultstring:ct10:cvrDefaultstring:skuSeries81x:pfaPiccoloSeries:

So let's remove the extra space. Crossing fingers... 🤞
