Even since the fixes of AST-2013-007, Asterisk prints the following
warning on startup if the user decided to live dangerously:

  Privilege escalation protection disabled!
  See https://wiki.asterisk.org/wiki/x/1gKfAQ for more details.

This message is intended for the logs and interactive startup. No need
for it to appear on a remote console. This commit removes it from there.
