bootstat: refine "Kernel panic - not syncing"
Provide some easy kernel panic subreasons mined from last kmesg,
generates a canonical boot reason (system boot reason) that
may aid triage.
Notably report kernel_panic,hung if [khungtaskd] triggers on
a livelock condition, forms a signals on the dashboards.
Helper function getSubreason modified to optionally enable checking
for a single quote resulting in a refactoring to ease maintenance of
the termination detection in the face of single bit errors heuristics.
Test: boot_reason_test.sh
