drivers: Fix upekts/upek_proto license

The (trivial) CRC code was copied from gstreamer. However, the license
stated here was LGPLv2 rather than LGPLv2.1+. Identical code can currently
be found upstream in gstreamer licensed under LGPLv2+. As such, update
the license, making it more compatible with the rest of libfprint.

Also add the "or any later version" to upekts.c. The library was already
LGPL2.1+ at the time and libthinkfinger authors approved a license
change.
