RFR: Runner: if -Djmh.ignoreLock=true then skip jmh.lock creation [v2]

[Sergey Ponomarev]

> When -Djmh.ignoreLock=true JMH anyway will try to create the jmh.lock file and if it fails it will write a warning for an user.
> This may be not a best way for several reasons:
> 1. If user specified ignoreLock then he already knows what she or he doing.
> 2. If the Benchmark is started from IDE i.e idea-jmh-plugin and the ignoreLock was added automatically then users may be confused by this warning
> 3. It makes execution slightly longer when we anyway trying to create the jmh.lock file
> 4. This simplifies logic
