host: link the renamed hermesvm prefab module on Android

React Native renamed the prefab module published by `hermes-engine` from
`libhermes` to `hermesvm` between 0.81 and 0.83 — the Android counterpart
of the `hermesvm` framework this branch already links against on Apple
platforms. This CMakeLists has been on `libhermes` since #308, which was
correct while the repo targeted 0.81, and stayed behind when this branch
jumped to 0.87/0.88.

Without it CMake fails to configure:

    Target "node-api-host" links to target "hermes-engine::libhermes" but
    the target was not found.
