build(jetsocat,dgw): optimize binary size (#1489)

CBenoit · web-flow · commit 8ad7ea0e96b1 · 2025-09-09T17:53:50.000Z
Size was already optimized in the past by enabling lto and stripping the
debug symbols. Adding codegen-units = 1 brings the binary size further
down.

- Jetsocat baseline: 7.3M
- Jetsocat after: 6.6M

- Devolutions Gateway baseline: 27M
- Devolutions Gateway after: 25M
