[Keyboard] Cannon Keys Satisfaction75: Fix buffer sizes for sprintfs. (#6954)

sprintf always adds a NULL terminator at the end of the buffer it works on.
A few places made just enough space for the resulting string, but not the terminator.
So this just adds one to the buffer size to make room for it.
