The validation checks that the values that were just assigned, got
assigned i.e. the error can't ever happen. Subsequent patches will call
this code in places where errors are not being returned. Changing those
code paths to return this non-existent error is counter-productive, so
just remove it.
That in turn results in perf_evlist__set_maps not needing to return an
error, but callers aren't checking it either, so remove that too.

With the previous patch, the installation method change from install
to rsync. There is no need to create subdir during test, the
default EMIT_TESTS is enough.
This patch essentially revert commit 84cbd9e4 ("selftests/exec: do not
install subdir as it is already created").

The command of install could not handle the special files in exec
testcases, change the default rule to rsync to fix this.
The installation is unchanged after this commit.

Commit 2bf9e0ab08 ("locking/static_keys: Provide a selftest")
renamed jump_label directory to static_keys and failed to update
the Makefile, causing the selftests build to fail.
This commit fixes it by updating the Makefile with the new name
and also moves the entry into the correct position to keep the
list alphabetically sorted.

This adds support for s390 to the seccomp selftests. Some improvements
were made to enhance the accuracy of failure reporting, and additional
tests were added to validate assumptions about the currently traced
syscall. Also adds early asserts for running on older kernels to avoid
noise when the seccomp syscall is not implemented.
