No substantial code change.
Note that some style errors reported by `golint` are not fixed due to possible compatibility issues.

The path in the stacktrace might not be:
"github.com/opencontainers/runc/libcontainer/stacktrace"
For example, for me its:
"_/go/src/github.com/opencontainers/runc/libcontainer/stacktrace"
so I changed the check to make sure the tail end of the path matches instead
of the entire thing
