Declare -realtime as deprecated

Browse source 
The old -realtime mlock=on|off parameter does exactly the same as the
new -overcommit mem-lock=on|off parameter. Additionally, "-realtime"
does not activate any additional "realtime" capabilities as the name
might indicate. We should avoid to confuse the users this way, so
let's deprecate the old -realtime option.
