perf stat: Change to --inherit option

The perf stat has -i/--no-inherit option.  However not only it's
confusing to have a default-to-negative option but also the short -i
option would be used for other purpose like all other perf commands.

So switch it to --inherit option and make it true to keep the current
behavior.  Users still can use --no-inherit but they'll see an error
message when use -i option.

The short -i option will be used to pass input data file later.
