For archived files the Chart.yaml file should be contained in a base
directory. This commit adds an error when the Chart.yaml file is found
in the root directory.

fix(helm): fix tests if tmp directory is on another block device

Two non-exported helper functions were added to the repo index test
file. They first try to link the file, since this is optimal. If the
link fails a copy occurs.

Fixes #1472

fix(tiller): allow 3rd party APIs

This feature has been disabled in the past because simply enabling the
feature causes the Kubernetes library to make requests to a server.
Thus, running any tests that use the 'pkg/kube' library has required
running a kube API server.

This patch makes it possible to selectively activate 3rdParty API
support, and then disables that support during testing.

Future versions of the Kubernetes library appear to make it easier to
configure and mock this behavior, so this is most likely a stop-gap
measure. (Famous last words.)

Closes #1472
