bpftool-native: Fix build on arm64 hosts with linux-libc-dev 7.3

Debian 13 now ships linux-libc-dev 7.3, where the arm64 UAPI headers
(asm/ptrace.h, asm/sigcontext.h) use __u128 instead of __uint128_t.
bpftool-native builds against the host headers but puts
tools/include ahead of them, and the 6.16 tools linux/types.h does not
define __u128:

/usr/lib/linux/uapi/arm64/asm/sigcontext.h:81:9: error: unknown type name '__u128'; did you mean '__u32'?

Backport the upstream tools/include/linux/types.h fix that adds the
128-bit types.

+Subject: [PATCH] tools: linux/types.h: Add 128-bit integer types for arm64 UAPI
+ structures
+
+The arm64 UAPI exposes some 128-bit integer types to represent things
+such as fpsimd registers in the sigcontext. In preparation for defining
+these using the '__u128' typedef implemented by uapi/linux/types.h, copy
+that typedef over to the private linux/types.h header used by the tools
+directory.

+Debian 13 now ships linux-libc-dev 7.3, whose arm64 asm/ptrace.h and
+asm/sigcontext.h use __u128. bpftool-native picks up
+tools/include/linux/types.h ahead of the host linux/types.h, so the
+build fails on arm64 hosts with "unknown type name '__u128'".
