Multiple `-J` flags don't seem to work

[Alex Clemmer]

With the example guestbook in the components/ directory, doing something like:

../kubecfg update dev -J lib -J ../lib

Results in an error that we can't find the example.libsonnet file. Reversing the order of the -J flags seems to cause kubecfg.libsonnet to go missing.

hah, oops. I know specifying multiple paths via the env var works, since I use that all the time. I'm surprised/disappointed that I have never tried the same via multiple -J flags :(
