🐛 Fix arm64 build: serialise Go compilation to prevent QEMU segfault 🐛

Browse Source 
The arm64 build was failing with:
github.com/caarlos0/go-version: .../linux_arm64/compile: signal: segmentation fault
Under QEMU emulation, parallel Go package compilation creates memory
pressure that causes the compiler to crash. Setting GOFLAGS=-p=1 on
aarch64 serialises compilation, eliminating the segfault. amd64 builds
are unaffected (no flag set on x86_64).
- rootfs/root/docker/setup/05-custom.sh: detect aarch64 via uname -m
and export GOFLAGS=-p=1 before all go install calls
