fix(git-gate): install the gitleaks binary for the build's target arch

The gateway Dockerfile hardcoded the linux_x64 gitleaks download, so an
image built on/for aarch64 (Apple Silicon) baked in an x86_64 binary.
It sat quiet until the git-gate pre-receive hook first invoked it, where
the kernel refused the foreign-arch exec — `gitleaks: Exec format error`
— failing every push through that gateway.

Pick the asset + pinned SHA from the build's target architecture:
TARGETARCH (auto-populated by BuildKit) with a `dpkg --print-architecture`
fallback for a legacy builder, and hard-fail on any unsupported arch.
Each arch keeps its own SHA256 verification, so no supply-chain regression.

The existing integration test test_gateway_image.py::
test_gitleaks_binary_present_and_versioned execs `gitleaks version` in the
built image, so it now passes on arm64 instead of hitting the same error.
