build: fix building with system icu 76

cho-m · RafaelGSS · commit 4887214e2359 · 2024-11-01T16:00:14.000-03:00
ICU 76 decided to reduce overlinking[^1] thus `icu-i18n` will no longer add `icu-uc` when linking to shared libraries. This results in undefined symbols/references when trying to build with system ICU 76.
