Update dependencies to libusb1

The runtime requirement was switched a while ago to a choice of
libusb-0.1 and libusb-1.0.  Since nowadays the 0.1 API is provided by a
compat shim on top of 1.0, better to just use that directly.  The -devel
package is no longer required to build though since no binding is built;
the library is loaded through ctypes.

Also, run the tests in accordance with Python packaging guidelines.
