Refactor RedHat support:
...
- Isolate file check to different elif (allowing to add more)
- Do the PTI debugfs check first (faster and supposed to be dynamic)
- If pti_enable is 0, don't trust dmesg (supposed to be dynamic)

Improve "running as root" check
...
Small issue with the USER environment variable:
$ echo $USER
thib
$ sudo sh -c 'echo $USER'
thib
$ sudo -i sh -c 'echo $USER'
root
Rather than recommending users to use sudo --login / -i, use the (very
widespread/portable) id program to retrieve the effective user ID
instead and don't change the recommendation.
$ id -u
1000
$ sudo id -u
0
$ sudo -i id -u
0
