* crunch-dispatch fetches the requested SDK version into its internal
git repository, just like it does for the Crunch script. Refactored
crunch-dispatch to make that code reusable.
* crunch-job's main script archives the sdk subdirectory as of that
commit, sending it along to compute nodes in the same .tar as the
Crunch script, under .arvados.sdk.
* crunch-job's __DATA__ dispatch section looks for the SDK under
.arvados.sdk, and installs it as much as possible.
Since I was messing with it so much already, I changed the semantics
of crunch-job's __DATA__ section: it is now either in installation
mode or run mode, based on whether there's anything in @ARGV. I
confirmed that this is consistent with current calls to the section.
