Use Framelayout instead of RelativeLayout in DialtactsActivity

Switch to FrameLayout instead of RelativeLayout since we don't need
the more complicated and expensive layout abilities of RelativeLayout.
This improves startup time (on hammerhead-eng, interpreted ART mode)
to about 1150ms on average from 1300ms originally.
