scripts/build/plugins: don't override CGO_ENABLED set by .variables 
The `.variables` sets `CGO_ENABLED=1` on arm; b0c41b78d8/scripts/build/.variables (L57-L68)
And if enabled, it sets `-buildmode=pie`; b0c41b78d8/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.
