Remove exec arg from utilipset.New

Browse Source 
Historically it took an exec argument so you could pass a FakeExec to
mock its behavior in unit tests, but it has a fake implementation now
that is much more useful for unit tests than trying to use the real
implementation with a fake exec. (The unit tests still use fake execs,
but they don't need to use a public constructor.) So remove the exec
args from the public constructors.
