runpod: fix a NameError in the provision path, and test for the whole class

The 150 GB warning's call site in _provision_one used a name that did not exist
in that scope. The helper was unit-tested and passed; every pod test then failed
in two seconds with "name 'entry' is not defined" before renting anything. A
helper can be correct while the line that calls it is not.

The entry is looked up the way the rest of the pool does it. And since pyflakes
sees exactly this class of bug, a test now runs it over the modules a pod boot
goes through, so an undefined name in that path fails the suite instead of the
first real request.
