Fix overlapping problem on running services page

For Android S, all pages support collpasing tool bar.
We add coordinatorLayout to work with collpasing tool bar
layout. And coordinatorLayout only works with RecyclerView
and NestedScrollView.
Unfortunately, the list was implemented by listView many years ago.

Because it's a very hidden page and the page is not maintained anymore,
we don't consider to migrate to RecyclerView.
Simply enable nested scrolling behavior for listview at this moment.

I also make some small refactorings in this cl.
1) Update the layout padding.
2) Format the xml file.
3) Create a individual cl for this page only.

Test: Don't see the overlapping problem
