Roll material-design-icons to 5ab428852e35dc177a8c37a2df9dc9ccf768c65a.

Commit 5ab428852e35dc177a8c37a2df9dc9ccf768c65a adds Contents.json for
all .imageset in the material-design-icons that are required for asset
catalog compilation.

Add //third_party/material_design_icons:ic_touch_app as a dependency
of //remoting/ios/app/resources:assets as it is now fixed.
