Fix the in-progress download status for the RTL UI.
Fix the in-progress download status for the RTL UI.

1. Make the download progress pie chart fill up CW even in the RTL UI. 
2. Make the filename be at the right end instead of being in the middle of the download status in the RTL UI.

BUG=13215,13216 (http://crbug.com/13215, http://crbug.com/13216)
TEST=1. Launch Chrome with --lang=he or --lang=ar. 
     2. Download a large file (like chrome mini-installer or Firefox) and go to the download tab (pressing Ctrl-J would work)
     3. The progress pie-chart should be filled up clockwise.
     4. The filename should be to the right of the download status ('5 kB of 7.2 MB - 4 mins left' in Hebrew or Arabic) instead of being put in the middle of the status string.
