make build should build kmeshctl

[hzxuzhonghu]

What would you like to be added:

Now when running make build, it does not build kmeshctl. We have to run make kmeshctl. I would think make build should build all the components

Why is this needed:

I thought to replace in Makefile:

.PHONY: build
build:
	 VERSION=$(VERSION) ./kmesh_compile.sh

OUT ?= kmeshctl
.PHONY: kmeshctl
kmeshctl:
	$(call printlog, BUILD, $(APPS4))
	$(QUIET) (export PKG_CONFIG_PATH=$(PKG_CONFIG_PATH):$(ROOT_DIR)mk; \
		CGO_ENABLED=0 $(GO) build -gcflags $(GOGCFLAGS) -ldflags $(GOLDFLAGS) -o $(OUT) $(GOFLAGS) ./ctl/main.go)

with

.PHONY: build 

OUT ?= kmeshctl

build: 
	VERSION=$(VERSION) ./kmesh_compile.sh
	$(QUIET) (export PKG_CONFIG_PATH=$(PKG_CONFIG_PATH):$(ROOT_DIR)mk; \
		CGO_ENABLED=0 $(GO) build -gcflags $(GOGCFLAGS) -ldflags $(GOLDFLAGS) -o $(OUT) $(GOFLAGS) ./ctl/main.go)

I tried this and it works fine and no test error.

@Insomniac2904 My mistake, seems build.sh is calling make in the container, but does not copy the built binaries to the host. We should fix the copy_to_host in hack/utils.sh
