Fix up job object options for unit tests (microsoft#1335)

Most of the `jobobject` package tests we have ask for options that aren't
actually needed/used. This change makes it so that any test that doesn't need
a named job object doesn't ask for one and any test that doesn't plan on
using the iocp messages doesn't flip the notifications field either. This
wasn't causing any issues, but it's probably best to filter down what's
being tested to only what's needed.

Additionally fixes TestExecsWithJob that used log.Fatal instead of t.Fatal
in the test.
