Fix padding in home page settings.

Fix padding in home page settings.

The "on"/"off" text and the switch were both too close to the edge of
the screen on pre-L devices. The bug arose because the LinearLayout had
conflicting padding attributes: it defined "padding" inline, and used a
style which defined "paddingStart" and "paddingEnd". The latter values
were overriding the inline "padding" value.
