After reading the background of bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1510922
It is not a problem actually, sorry for the noise.
Although root set different "PATH" can lead to wrong script, but it is different with what the bug described "current working dir" and it is not a problem worth an update.
Thanks Dave

Since we call dracut directly on current working directory "." so it is possible to trick root to call fake code.
Thus move to use abosolute path instead.
