Simplify cuda verifier tests and use StartTracer helper#244

Replace the debootstrap rootfs with a minimal busybox + ldd-based approach. Instead of downloading a full Debian minimal rootfs, we: - Use busybox-static for shell and utilities - Copy only the shared libraries actually needed (via ldd) - Copy libstdc++ and libgcc_s for parcagpu's dlopen chain Benefits: - No sudo required (debootstrap needs chroot) - Initramfs ~44MB vs ~96MB with debootstrap - Faster build (no network download of .debs) - No debootstrap apt dependency in the build job Tested locally: all tests pass on kernel 6.6.31.

InstrumentCudaLaunch Also remove CUDAVerifier tests as that is subsumed by the e2e tests and the arm tests take 5m with all that extra bpf verification going through qemu

Summary
TestCUDAVerifierSingleShotandTestCUDAVerifierMultiProbe— redundant since the e2e tests already load and verify the same BPF programsrunEndToEndwithtestutils.StartTracer, removing ~100 lines of boilerplateThis eliminates 2 full BPF program load+verify cycles, significantly reducing ARM test time (~5min previously).
