kernel-selftest: add generic architecture-independent self-tests

Add generic kernel self-tests that build cleanly with mainline
kernel (6.18+), work on all architectures, and either PASS or SKIP
gracefully at runtime.

Tests added:
- acct: BSD process accounting
- breakpoints: hardware breakpoint handling
- cachestat: page cache statistics (cachestat syscall)
- cgroup: control group v1 interface
- clone3: clone3 syscall with flags
- core: syscalls like close_range, unshare
- coredump: core dump generation
- dmabuf-heaps: DMA-BUF heap allocator
- efivarfs: EFI variable filesystem
- filelock: POSIX file locking (OFD locks)
- filesystems: basic filesystem operations
- filesystems/binderfs: Android Binder IPC (skips if CONFIG_ANDROID_BINDERFS=n)
- filesystems/epoll: epoll syscall extensions
- fpu: floating-point unit state
- ftrace: function tracer interface
- futex: fast userspace mutex
- gpio: general purpose I/O
- ipc: System V IPC primitives
- kcmp: compare kernel resource identifiers
- kvm: kernel-based virtual machine
- landlock: LSM sandboxing (skips if CONFIG_SECURITY_LANDLOCK=n)
- locking: ww_mutex deadlock avoidance
- lsm: Linux Security Module interface
- membarrier: memory barrier syscalls
- mincore: mincore syscall (page residency)
- mount: mount syscall (unprivileged variants)
- mount_setattr: mount attribute syscall
- move_mount_set_group: move_mount peer group
- mseal_system_mappings: system mapping sealing
- namespaces: PID/UTS/IPC/mount/network namespaces
- net: networking stack
- net/mptcp: multipath TCP
- pidfd: pidfd-based process management
- pid_namespace: PID namespace limits
- proc: /proc filesystem interface
- ptrace: process tracing
- rlimits: resource limits
- rseq: restartable sequences
- sched: scheduler and real-time classes
- seccomp: secure computing mode
- signal: signal handling
- size: ELF size utilities
- splice: zero-copy data transfers
- sync: cache synchronization
- syscall_user_dispatch: user-space syscall dispatch
- sysctl: sysctl interface
- tc-testing: traffic control
- timens: time namespaces
- tmpfs: tmpfs filesystem
- tpm2: Trusted Platform Module 2.0
- tty: TTY layer
- uevent: kernel uevent subsystem
- user_events: tracepoint user interface
- vDSO: virtual dynamic shared object
- watchdog: hardware watchdog timer
- zram: compressed RAM block device

Tested on aarch64 device BeaglePlay(AM6254 SoC):
- Tests either PASS or SKIP gracefully
