The `.variables` sets `CGO_ENABLED=1` on arm; https://github.com/docker/cli/blob/b0c41b78d8c80c5f8faa736cf3c74dc31092e443/scripts/build/.variables#L57-L68
And if enabled, it sets `-buildmode=pie`; https://github.com/docker/cli/blob/b0c41b78d8c80c5f8faa736cf3c74dc31092e443/scripts/build/.variables#L79-L88
But that looks to be conflicting with the hardcoded `CGO_ENABLED=0` in
this script, which causes the build to fail on go1.22;

0.135 -buildmode=pie requires external (cgo) linking, but cgo is not enabled
This patch sets the CGO_ENABLED variable before sourcing `.variables`,
so that other variables which are conditionally set are handled correctly.
