[Autotest] add policy_DeviceTargetVersionPrefix test

Add a test to verify the client update request behavior when
the DeviceTargetVersionPrefix policy is set.

The three cases are:
- policy is not set, so the initial update request does not
    contain targetversionprefix
- policy is set to a full build number, so the request
    contains the first two numbers (e.g. 9999.99.)
- policy is set to a partial build number, so the request
    contains the partial number (e.g. 9999)

TEST=ran all three cases on several lab machines
BUG=None
