hw/usb/host-libusb.c: fix build with kernel < 5.0
USBDEVFS_GET_SPEED is used since version 5.2.0 and
https://gitlab.com/qemu-project/qemu/-/commit/202d69a715a4b1824dcd7ec1683d027ed2bae6d3
resulting in the following build failure with kernel < 5.0:
../hw/usb/host-libusb.c: In function 'usb_host_open':
../hw/usb/host-libusb.c:953:32: error: 'USBDEVFS_GET_SPEED' undeclared (first use in this function); did you mean 'USBDEVFS_GETDRIVER'?
int rc = ioctl(hostfd, USBDEVFS_GET_SPEED, NULL);
^~~~~~~~~~~~~~~~~~
USBDEVFS_GETDRIVER
A tentative was made to fix this build failure with
https://gitlab.com/qemu-project/qemu/-/commit/4969e697c15ac536d5c0700381d5d026ef7f0588
However, the assumption that distros with old kernels also have old
libusb is just wrong so also add a check for defined(USBDEVFS_GET_SPEED)
