Deduplicate a helper function in android/ntp

The function GetRemoteSuggestionsScheduler was defined
twice which caused some problems for jumbo build experiments.

In jumbo builds many cc files compile in the same translation
unit and then they share the same anonymous namespace. Having
a function twice (with the same name) will then result
in compilation failures.

In preparation for jumbo in chrome/browser, this patch moves the
helper function to its own file because no existing place seemed
to work fine.
