Fixed a label alignment issue in ConfirmMessageBoxDialog. 

There is no need to manually detect the text directionlity at run time. Setting the
label's alignment to views::Label::ALIGN_LEFT is sufficient because the mirroring subsystem
will flip it automatically if the locale is RTL.

BUG=26378
TEST=Run chrome with --lang=he, enable sync and then disable through the options dialog. Text in dialog box should be right aligned.
