All printers list has incorrect padding and item height.

1. We were using the layout for the printer drop down from the
   print dialog as the list item in the all printers activity.
   This layout was not high enough. Now we have a separate
   layout for the drop down and for the list. Note that they
   are almost identical but this is better that writing java
   code to lookup the height from the theme and change it
   programatically since the java code is almost half the size
   of the layout and leads to spreading the logic in both the
   layout file and the java code.

2. The padding of the printers list was not correct. Now it
   mimics the bahavior in settings where we change the padding
   based on orientation.
