Code Issues Proposed changes

Update SCHEDSTAT_SUPPORTED_VERSION to match kernel 6.12

Browse Source 
Linux kernel 6.12 updated /proc/schedstat version to 16. As a result
collectd and schedtop fails to get sched statistics.
This change updates collect scripts with the required version.

Test Plan:
PASS: Fresh install
PASS: <sudo schedtop --idle> executes with no errors
PASS: no errors in /var/log/collectd.log related to schedstat version

Closes-Bug: 2111949
