Formatting: removed variable redeclaration in CGPath.j

Variables `arcStartX` and `arcStartY` are declared on 125 and 126, but
are later redeclared in an `else` statement on lines 135 and 136 with
the same equation and presumably the same value used in the initial
declaration.
Also added missing semi-colon
