Option 82 logging on dhcpd 4.1.1 and red hat 6

[Glenn Satchell]

There may be non-ascii characters in your option agent.circuit-id, so try
a suitable binary-to-ascii() around it. If there is a non-ascii or null it
won't print anything.

The parenthesis around a variable make no difference, they just control
order of parameters.
