hostname obfuscation in /sys/kernel/debug/sched/debug

[arif-ali]

As part of the migration of the ubuntu package and a sync from debian yesterday we found that we can see the hostname in the file /sys/kernel/debug/sched/debug.

In this particular scenario, the hostname was autopkgtest, and a potential process was running with the name autopkgtest-run

the migrattion to ubunu dev went through, but we ought to resolve this, and we either catch it with update on the obfuscation or this should be ignored.

Note: we are still using simple.sh for tests here, due to the fact avocado is still not packaged in Debian and Ubuntu, we are actively working to address. Once that is done, we can get rid of this simple.sh for validation
