r36187 broke auth in mysql.lua (protocol version 10)

[cldrn]

I just noticed mysql-brute is not working. Something broke authentication in r36187. Scripts works correctly if I revert to r35858.

Tested on MySQL 5.7.13 using protocol version 10.

@cldrn Thanks for pointing this out! A couple observations, and I hope someone can quickly diagnose:

1. We also apparently need to strip carriage returns ('\r') from the Salt when reporting that. That's the weird jumbled-up line after "Status: Autocommit"
2. For future reference, the commit in question is 8c10485, which fixed wrongfully reading version #529
