[PATCH 3/3] gcc-plugins: pinpoint: move to subdirectory

[Kees Cook <kees@kernel.org>]

Pinpoint adds 35 files directly to scripts/gcc-plugins/, a directory
shared with the other plugins, using generic names such as serialize.c,
passes.h, layout_hash.c and target_registry.c, plus twelve safe-*.h
wrappers. Move them into scripts/gcc-plugins/pinpoint/ so they no longer
crowd the shared namespace, matching how the rest of the series is laid
out (kernel/spslr/, samples/spslr/tasklist/).

Build tested ARCH=x86_64 defconfig+CONFIG_SPSLR=y with the patched
GCC 16.1.0 / GAS 2.46.1 toolchain, using O= (out-of-tree). Boot tested
under QEMU to a busybox userspace: two randomized boots and one
"nospslr" control all reach userspace and complete a task_struct
exercise (ps, /proc/self/{stat,status}, 200 fork+execs, signals, pipes,
timers) with zero oops/BUG/WARNING.
