qemu: Disable libudev for QEMU 5.2 and newer

Browse Source 
Commit 112ea25859 disabled libudev for static builds because it was
breaking snap. It turns out that the only users of libudev in QEMU are
qemu-pr-helper and USB. Kata already disables USB and doesn't use
qemu-pr-helper. Disable libudev for all builds if QEMU supports it, i.e.
version 5.2 or newer.

Fixes #3078
