#13811: LazyFamily cannot be copied if it can't be pickled

Currently, copying of `LazyFamily` objects only works for families that
can be pickled:
{{{
sage: def unpicklableFamily():
... x = 10
... return LazyFamily([1,2,3], lambda n: x*n)
sage: f = unpicklableFamily()
sage: copy(f)
Traceback (most recent call last):
...
ValueError: Cannot pickle code objects from closures
}}}
I suggest adding a `LazyFamily.__copy__` method that fixes this.
