Yong Tang 77f8e3ea0c Fix /proc/<pid>/oom_score_adj: invalid argument error caused by empty env name ...

This fix is part of the fix for issue 25099. In 25099, if an env
has a empty name, then `docker run` will throw out an error:
```
ubuntu@ubuntu:~/docker$ docker run -e =A busybox true
docker: Error response from daemon: invalid header field value "oci runtime error:
container_linux.go:247: starting container process caused \"process_linux.go:295:
setting oom score for ready process caused \\\"write /proc/83582/oom_score_adj:
invalid argument\\\"\"\n".
```

This fix validates the Env in the container spec before it is sent
to containerd/runc.

Integration tests have been created to cover the changes.

This fix is part of fix for 25099 (not complete yet, non-utf case
may require a fix in `runc`).
This fix is related to 25300.
