Add kselftest to test that remove_on_exec removes inherited events from child tasks.

To make compatible with more recent libc, we'll need to fixup the tests with the below.
Also, I've seen that tools/perf/tests exists, however it seems to be primarily about perf-tool related tests. Is this correct?
I'd propose to keep these purely kernel ABI related tests separate, and that way we can also make use of the kselftests framework which will also integrate into various CI systems such as kernelci.org.
Perhaps there is a way to have both? Having the perf tool spot an errant kernel feels like a feature. There are also tools/lib/perf/tests and Vince Weaver's tests [1]. It is possible to run standalone tests from within perf test by having them be executed by a shell test.
Thanks, Ian
