autotest: Validate netblock strings before parsing
Consolidate all construction paths into a single helper function and
do some limited validation of passed in arguments before attempting to
parse them. This should get us more meaningful messages when tests
attempt to use invalid netblock strings in logic.
BUG=chromium:433621
TEST=network_BasicProfileProperties still passes.
