MFC r361977: libusb: improve compatibility

Specifically, add LIBUSB_CLASS_PHYSICAL and the libusb_has_capability API.
Descriptions and functionality for these derived from the
documentation at [0].  The current set of capabilities are all supported by
libusb.

These were detected as missing after updating net/freerdp to 2.1.1, which
attempted to use both.
