util: usb: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

Browse Source 
Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in
src/util/viralloc.h, define a new wrapper around an existing
cleanup function which will be called when a variable declared
with VIR_AUTOPTR macro goes out of scope. Also, drop the redundant
viralloc.h include, since that has moved from the source module into
the header.

When a variable of type virUSBDevicePtr is declared using
VIR_AUTOPTR, the function virUSBDeviceFree will be run
automatically on it when it goes out of scope.
