OpenGL2: Fix parsing q3gl2_sun without two additional tokens

Browse source 
If mapLightScale and shadowScale weren't included at the end of
q3gl2_sun, the next shader line was skipped by SkipRestOfLine().

COM_ParseExt() with allowLineBreaks=qfalse, returns "" once and
then goes to the next line anyway. (Doesn't work well multiple
"optional" tokens. It looks like a vanilla bug.)
