sasl: fix zero-length response encoding
A sasl zero-length normal response is an empty string, unlike an initial
response. Since the encoding of a zero-length initial response is
protocol dependent, move its handling to the protocol-specific sendauth
procedure. Similarly, do not check for an '=' server message, as this
should normally never occur.

Update the erroneous tests accordingly.

Closes #22218
