Improve PTI detection even more
...
when PTI detection relies on dmesg, dmesg output is checked first
then /var/log/dmesg if dmesg output lacks boot time messages

Improve PTI detection
...
In case of a busy or misconfigured server, kernel message buffer loop
can be filled with messages broadcasted later than boot time. So dmesg
command wont return boot time messages.
Grepping /var/log/dmesg fixes it and this log file location semms pretty
standard across many common distros

Small issue with the USER environment variable:

$ 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
