Patch to correct this bug

Description of problem:
"spacewalk-channel" from (rhn-setup-0.4.20-56.el5) reads the username from stdin if not presented on the commandline, however it does not truncate the newline from the input.

    if not OPTIONS.user and not OPTIONS.list:
        print("Username: ")
        OPTIONS.user = sys.stdin.readline()

This results in all usernames being rejected as such:
# spacewalk-channel -c epel-x86_64-5 -a 
Username: 
rkeene
Password:
