Change logserver to only print an error log if it fails

[g-linville]

The info log that was getting printed at the start of this caused several of our e2e tests to fail last night because they were not expecting that to be present in the output. There's very little that can go wrong while starting this thing anyway, so I think it makes more sense to just log and error if there is one, and otherwise be silent.
