Subject: [PATCH] [android] add library `libcutils` for compiling ot-cli and
 ot-ncp (#6104)

When compiling ot-cli and ot-ncp, the Android.mk will compile
the function `property_get` in `src/core/api/instance_api.cpp`.
The function `property_get` is provided by the library `libcutils`.

GitHub Action uses Android NDK to compile Android.mk, Android NDK
only allows adding the shared library `libcutils` for the library
`ot-core`. However, Android requires to add the shared library
`libutils` for the binary `ot-cli` and `ot-ncp`. Therefore, this PR
uses the macro `ANDROID_NDK` to distinguish these two cases.
