RFR: 8376630: java/lang/ProcessBuilder/PipelineLeaksFD.java intermittent timed out [v2]

[SendaoYan]

> Hi all,
> 
> Test java/lang/ProcessBuilder/PipelineLeaksFD.java intermittent timed out, because `lsof` invoke huast lots of time when the tested machine has many processes, and the processes open too many files.
> 
> This PR add parameter -p pid to `lsof`, which will only generate output from the wanted processes, rather than all the processes on the machine, this will make `lsof` use less time to finish significantly. And this PR also use `Process.waitFor(long timeout, TimeUnit unit)` instead of `waitFor()` which will avoid waitFor invoke cause test timed out. Delete the history lsof input and output files will make diagnosis more easy.
> 
> Change has been verifed locally. The imtermittent timed out do not observed anymore.
