feat: Modify layer build process

After compile-layer build, there should be a new container for distro-layer.
So do flock-layer.
These three layer's environemnt are different. However, the container is hard to change environment after launched.
So, Three layers, three environments and three containers.

The process is

cp localrc-compiler localrc
./tb.sh env
./tb.sh run
./tb.sh exec

cp localrc-distro localrc
./tb.sh env
./tb.sh run
./tb.sh exec

docker ps | awk 'NR>1{print $12}'
stx-distro-centos-builder
stx-compiler-centos-builder
