C++ false-positive

描述

We just started using https://github.com/firehol/netdata in LGTM. Thank you!

We found that LGTM reports `cpp/command-line-injection` false positives.

Here is a screenshot:

But the code is the other way around: We use `fgets()` after we run the command, to read the output of the program we execute, like this:
