Hisham Muhammad 47cf1532b0 Linux: change how kernel threads are detected
Use the same method that ps and top use to determine if a
process is a kernel thread on Linux: check if cmdline is empty.

Thanks to @wangqr's investigation reported here:
https://github.com/hishamhm/htop/issues/761#issuecomment-375306069

Fixes #761.
