fix(virt-handler): import full qemu-bins directory and add qemu-img binary

Import /qemu-bins instead of /qemu-img from the qemu image to include
all necessary QEMU binaries. Add /usr/bin/qemu-img to the binaries list
and change import phase from "after: setup" to "before: setup" to ensure
binaries are available during the setup phase.
