pkg/report: improve parsing of task hung reports

The problem with task hung reports is that they manifest at random victim stacks,
rather at the root cause stack. E.g. if there is something wrong with RCU subsystem,
we are getting hangs all over the kernel on all synchronize_* calls.
So before resotring to the common logic of skipping some common frames,
we look for 2 common buckets: hangs on synchronize_rcu and hangs on rtnl_lock
and group these together.
