Fix RTL label alignment in select SIM dialog

The default text alignment of a TextView is based on the content of the view (does it has any RTL characters or not). Previously the TextView width is match parent so the text will either align to the left or right depending on the content (the label is user content which we don't control). In this CL it is changed to wrap content so the whole text will align to the parent's gravity which is "start".
