fix erlang-mode erlang-get-function-arity
In the emacs erlang-mode the function erlang-get-function-arity failed to return a correct arity value for functions with literal binaries as parameters, for example: function(<<Bin:20/binary>>) -> Bin. Fix erlang-get-function-arity to recognize binary parameters correctly.
