usb: net: update README.usb to list all USB ethernet options
- extend the discussion of USB network related config options such that
all available adapter drivers are listed, and that the 'usb' command
for the interactive prompt and scripting becomes available
- suggest to *not* put individual IP configuration parameters into the
exectuable, but instead to put them into external environment or fetch
them from network
