It turns out arm32 doesn't handle syscall -1 gracefully, so skip testing for that. Additionally skip tests that depend on clone3 when it is not available (for example when building the seccomp selftests on an old arm image without clone3 headers). And improve error reporting for when nanosleep fails, as seen on arm32 since v5.15.
