USB: Allow usbmon as a module even if usbcore is builtin 

usbmon can only be built as a module if usbcore is a module too. Trivial
changes to the relevant Kconfig and Makefile (and a few trivial changes
elsewhere) allow usbmon to be built as a module even if usbcore is
builtin.

This is verified to work in all 9 permutations (3 correctly prohibited
by Kconfig, 6 build a suitable result).

If you say Y here, a component which captures the USB traffic
If you select this option, a component which captures the USB traffic
between peripheral-specific drivers and HC drivers will be built.
For more information, see <file:Documentation/usb/usbmon.txt>.
This is somewhat experimental at this time, but it should be safe.
If unsure, say Y.
If unsure, say Y (if allowed), otherwise M.
