Return firmware version parts as uint8_t instead of int

The firmware version parts returned by the Nitrokey devices are uint8_t
values.  This is part of the public API as part of the NK_storage_status
struct.  For consistency with this API, this patch changes the functions
NK_get_major_firmware_version and NK_get_minor_firmware_version to
return uint8_t instead of int.
