[Crash-utility] [PATCH] add -t option for runq command

Hi Dave， I agree with your opinion，the first suggestion (1) seems better.I have already accepted your specification and modified the patch. Specific modification as follows: (1) The option “-t” is accepted, while the option "-c" was abandoned. (2) Turn key word '*_clock' into '*_timestamp'. (3) Add information about active task on each cpu，like this： CPU 0: 67393251944103 [67393251944103] PID: 14776 TASK: ea54aab0 COMMAND: "crash" CPU 1: 66789719628339 [67393251858710] PID: 14769 TASK: f4bdc030 COMMAND: "crash" Do you have any other suggestion or requirement? Regards, Wei Jiangang
