Fixes build error on iOS.

Upstream added code for Android (and not in cr129 yet) for iOS, but the
inlcudes aren't guarded for the those platforms. The dependency is
missing in upstream code.

    [M129] Disallow VerbatimMatches to open non-navigable URLs by default.

    This change prevents non-navigable URLs from being opened upon paste,
    refine, autocomplete etc., effectively disallowing accidental execution
    of inline javascript: blocks.

    The non-navigable (e.g. executable) URIs will be effectively pushed
    down on the suggestions list, making them still available, but
    moving forward these will require an explicit user action to be
    invoked (i.e. the user now has to intentionally tap these suggestions
    to initiate the corresponding action).

    The change removes redundant test that relies on inline page
    injection. This is already covered by another test:
