Redirecting the output of gztopic hz to a file does not work

[osrf-migration]

The output is produced using printf and the output is not flushed when a file redirection is applied. Example:

#!c++

gztopic hz /gazebo/default/world_stats > log

The same problem happens when gztopic hz is combined with another command using a pipe.

Prefixing unbuffer to the command fixes the problem but I guess this is a Linux specific solution.

I propose to replace printf by cout to solve this issue.

See pull request #854.
