shell/lib: moving shell libraries into the veyron core repository

This CL moves shell libraries into the veyron core repository and
provides a mechanism for looking up the location of the shell
libraries (and veyron Go package directories) that is independent of
VEYRON_ROOT.

Doing so enables running integration tests after veyron sources were
fetched using the "go get" mechanism.
