This fix tries to address the warnings caused by static build with go 1.9. As systemd needs dlopen/dlclose, the following warnings will be generated for static build in go 1.9: ``` root@f4b077232050:/go/src/github.com/opencontainers/runc# make static CGO_ENABLED=1 go build -tags "seccomp cgo static_build" -ldflags "-w -extldflags -static -X main.gitCommit="1c81e2a794c6e26a4c650142ae8893c47f619764" -X main.version=1.0.0-rc4+dev " -o runc . /tmp/go-link-113476657/000007.o: In function `_cgo_a5acef59ed3f_Cfunc_dlopen': /tmp/go-build/github.com/opencontainers/runc/vendor/github.com/coreos/pkg/dlopen/_obj/cgo-gcc-prolog:76: warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking ``` This fix disables systemd when `static_build` flag is on (apply_nosystemd.go is used instead). This fix also fixes a small bug in `apply_nosystemd.go` for return value. Signed-off-by: Yong Tang <yong.tang.github@outlook.com>
