Wait some more before giving up

Yukin observed a case on a baremetal server where the install failed
with:

In fact the install proceeded just okay, we just gave up too early.
Let's double the amount of times we wait for this and also increase the
wait in between tries by 5 seconds. Hopefully this should cover these
edge cases.
