android: TETHER_FEATURES switch in build-android.sh (build the iroh core)

Browse Source 
Mirrors build-apple.sh: TETHER_FEATURES=iroh-transport ./build-android.sh builds
libtethercore.so with the iroh stack. Verified: .so builds for arm64-v8a + x86_64
(2378 iroh symbols in the arm64 .so) and Kotlin bindings generate. Android joins
the build-verified-on-iroh set; only the web/WASM target remains.
