xray-core: fix service start / reload

Fix starting problem:
Starting function should be named 'start_service' instead of 'start_instance'.

Fix reloading problem:
Register reload tigger for uci config itself.
And, xray does not support reload currently, so use legacy restart as reload.

Fixes: 6c9b96352f ("xray-core: add init script")
