Fix missing libusbredirparser1

[tlex]

Currently, the device usb-redir isn't available due to a missing library. This commit fixes that.

$ docker run --rm -it tianon/qemu:latest bash
root@c13622dfc6bf:/# qemu-system-x86_64 -device help|grep redir
Failed to open module: libusbredirparser.so.1: cannot open shared object file: No such file or directory

However, once the package libusbredirparser1 is installed, the device is available:

root@c13622dfc6bf:/# apt-get -qq update && apt-get install libusbredirparser1

Please note this only affects QEMU 5.1, the library is properly linked to the older versions.
