automation: qemu-smoke-arm64: Use kernel 5.19

Use kernel 5.19 to unblock testing dom0less enhanced.
This kernel version has the necessary patches for deferring xenbus probe
until xenstore is fully initialized.
Also, build kernel with bridging and xen netback support enabled because
it will be used for testing network connectivity between Dom0 and Dom1
over a pv network interface.
