xigang / build_contianerd.sh

build containerd Dependency package

	You need the following packages installed.
	btrfs-progs-devel-3.16.2-1.el7.x86_64
	btrfs-progs-3.16.2-1.el7.x86_64

	In the absence of that you can do a make docker-build
	I also checked in conditional compilation for btrfs if you don't have the packages installed. So if you get the latest, you should be able to build without the btrfs packages.
