loxilb go code build error in BPFire chroot build environment

[vincentmli]

Describe the bug

I am able to build loxicmd in BPFire chroot build environment, but not loxilb. this is unlikely bug in loxilb but golang in chroot build environment, but would like to know if there is workaround in loxilb to avoid this problem

two problems:

1. loxilb go.mod:3: invalid go version '1.22.0': must match format 1.23

BPFire has golang 1.20.4 installed in chroot build environment, loxilb go.mod has 1.22.0 requirement, it seems cause above mismatch? see error vincentmli/BPFire#19

2. loxilb main.go build error GOPROXY list is not the empty string

I upgraded BPFire golang from 1.20.4 to 1.22.0 to meet loxilb go.mod requirement, but then had this main.go:24:2: GOPROXY list is not the empty string, but contains no entries, see vincentmli/BPFire#17, google search shows golang upgrade could result in this problem, not sure how to workaround this issue.

To Reproduce
Steps to reproduce the behavior:

Environment (please complete the following information):

• OS: Ubuntu 22.04 to build BPFire loxilb addon in chroot

• LoxiLB Version: 0.9.4-beta

Additional context
Add any other context or topology about the problem here.

it is better to build loxilb in BPFire chroot environment as BPFire software addon, build loxilb and copy binary to BPFire OS seems not ideal

[vincentmli]

I used go mod vendor for loxilb and loxicmd to get the golang packages dependencies which created vendor under loxilb and loxicmd, this avoid to download the golang packages, and avoid the GOPROXY list is not the empty string issue
