`rsproperties::get` panics when it can't open or parse the
`/dev/__properties__` layout (documented behavior of the crate).
On some older/unusual Android builds (e.g. MediaTek Android 8.1 on
Xiaomi Mipad), this aborts the app with SIGABRT before the main
window is created.
Replace the crate with a direct FFI call to Android's native
`__system_property_get`, which has existed since the earliest
Android versions and returns an error code instead of panicking.
