Issue #7766 uses .each_line instead of .each on an array.

I could not find where this got merged; since
https://github.com/theforeman/smart-proxy/pull/294
is still open.

At least with ruby 2.0, .readlines seems to become an array:

std_in, std_out, std_err  = Open3.popen3(command)
response  = std_out.readlines
response += std_err.readlines

Using each_line will result in a no method error:
