pingpong: reject nul byte in server response line

Browse source 
Add test 2108 covering the rejection over FTP. Drop the now-vestigial
nul bytes from test 1282; they exercised the removed Kerberos FTP
security buffer check and now trip this rejection before the 633
login-denied path is reached.

Closes #21996
