package/python-tftpy: add host variant

A host variant of python-tftpy will be needed for Snagboot, so enable
it, and add a very simple test for the host package. We considered
adding a test that actually starts a TFTP server with tftpy and then
downloads from that server with the client-side of tftpy, but
allocating an available UDP port reliably is tricky, so we kept the
test case very simple for now.
