docker info: fix condition for printing debug information

The daemon collects this information regardless if "debug" is
enabled. Print the debugging information if either the daemon,
or the client has debug enabled.

We should probably improve this logic and print any of these if
set (but some special rules are needed for file-descriptors, which
may use "-1".
