To make this apply at the beginning of the text (or of a word), I  
think you'd need

   \XeTeXinterchartoks 255 \cyrdash = {.....}

because 255 is the "reserved" class for "edge of text run".

An alternative approach, though, might be to replace the em-dash with  
an en-dash, or if that's too short, with two en-dashes kerned so as to  
partially overlap; this should let you get the appearance you want  
without requiring the graphicx package.
