2ro d95efef896 linux: build_release.sh produces a correct arm AppImage (per-arch runtime)
The arm path hardcoded ARCH=x86_64 and the x86_64 type2 runtime, so a
`build_release.sh arm` run produced a broken AppImage (x86_64 runtime wrapping
an aarch64 binary). Derive ARCH and the runtime file from the target arch, and
have toolchain.sh fetch runtime-aarch64 alongside runtime-x86_64. This restores
GRIM's linux-arm AppImage release type; verified the output is an ARM aarch64
AppImage.

# Goblin links the Nym SDK IN-PROCESS (src/nym/), so the AppImage is one

# Portable cross-build to glibc 2.17. Three zig-specific fixes:
# - CRoaring's AVX512 path won't compile under zig's clang (evex512 error).
# - OpenSSL is vendored in Cargo.toml, so no system libssl is needed.
# - v4l2-sys (camera/QR backend) runs bindgen over linux/videodev2.h, a kernel
# UAPI header missing from zig 0.12.1's glibc-2.17 sysroot; point bindgen at
# the host's kernel headers. This only reads struct layouts — the actual libc
# linkage stays glibc-2.17, so portability is unaffected.
