Fix init_tzdb forward declaration for Android with USE_OS_TZDB

alesapin · claude · alesapin · commit 68616cc50d12 · 2026-03-22T11:19:58.000+01:00
The forward declaration of `init_tzdb` was guarded by `!ANDROID`, but
the function definition exists under `USE_OS_TZDB` and has Android-specific
code. This caused a compilation error on Android when `USE_OS_TZDB=1`.
