The gocapability package uses /proc/PID/status to get a bounding set.
If a container uses pidns without mntns, it sees /proc from the host
namespace, but the process doesn't know its own pid in this namespace.
In this case it can use /proc/self/status, which is always the right one.

Also, updated .travis.yml to use the new "vendor" directory (since this is pretty pointless without that :D)
