Qiang Huang b167eafbb8 Handle error for dockerCmdInDir ...

Only two of these are not handled, the one in `TestBuildForceRm`
is intended to not be handled, while the other one in
`TestBuildResourceConstraintsAreUsed` causes problem.

In test case `TestBuildResourceConstraintsAreUsed`, somehow we
are not able to access network to get base image, but the error
message is:

```
Error: failed to inspect container : Unable to read inspect data: json: cannot unmarshal array into Go value of type types.ContainerJSON
```

Totally confusion.
