feat: replace Google NDK with monero-ndk v1.0.1

[Justxd22]

• Replace Google NDK blob (android-ndk-r28c, ~1.7GB) with from-source monero-ndk v1.0.1 (~150MB) built from LLVM/clang
• Drop 7zip and python@3.11 dependencies (no longer needed tarball extracts directly)
• Simplify build steps using SYSROOT_TRIPLE env var instead of per-arch copy commands
• Fix OpenSSL x86_64-linux-android config: split x86_64-linux* wildcard so Android doesn't match the desktop linux-x86_64 target

Update now it checkout monero-ndk and build from source, a test build is on the way

.download block should contain all dependencies, so make fetch should not be executed later - this is required for the builds to work offline
