minor changes for macos compatibility

conditionally comment out detaching usb device kernel drivers with apple builds
as macos makes this almost impossible to work - see libusb faq here:

https://github.com/libusb/libusb/wiki/FAQ#how-can-i-run-libusb-applications-under-mac-os-x-if-there-is-already-a-kernel-extension-installed-for-the-device-and-claim-exclusive-access

this change has been cherry picked from https://github.com/j4nn/xperable/pull/1
only the "macos port" commit from @m1zole, adapted as suggested in the comment
https://github.com/j4nn/xperable/pull/1#issuecomment-3716696929
