1. Fix vs check install login timeout issue (sonic-net#11727) …

   Why I did it
   Fix a build not stable issue: sonic-net#11620
   The vs vm has started successfully, but failed to wait for the message "sonic login:".
   
   There were 55 builds failed caused by the issue in the last 30 days.

   It is caused by the login message mixed with the output message of the /etc/rc.local, one of the examples as below: (see the message rc.local[307]: sonic+ onie_disco_subnet=255.255.255.0 login: )
   The check_install.py was waiting for the message "sonic login:", and Linux console was waiting for the username input (the login message has already printed in the console).

   How I did it
   Input a newline when finished to run the script /etc/rc.local.
   If entering a newline, the message "sonic login:" will prompt again.
