Enable more perf capabilities
- enable schedstats - allows for more perf events like
`sched:sched_stat_sleep` and `sched:sched_stat_iowait`
- enable kernel auditing - allows using `perf trace` - depends on
BR2_PACKAGE_AUDIT
- enable perf.data compression - allows using the `-z` switch - depends
on BR2_PACKAGE_ZSTD
Changes I made to the buildroot submodule:
1) Update to the latest `next` branch. That branch includes patches
which enable additional optional dependencies for perf.
2) Rebase our specific patches on top of the `next` branch.
3) Cherry-pick a fix for a regression from the `master` branch.
