loxilb: add loxilb load balancer addon

build loxilb in BPFire requires golang 1.22.0,
but then had issue [0], run go mod vendor to
prepare the loxilb to download golang dependencies
package beforehand to avoid issue [0]

loxilb-ebpf build also requires gnu/stubs-32.h
use [1] as workaround

[0]: #18
[1]: #16
