Fix enableVmCleanup not working for apps with product flavors. (#32422)

Summary:
Pull Request resolved: #32422

While working on the NDK AGP Api I realized that the `enableVmCleanup` function,
that is supposed to cleanup the extra `.so` files from the final artifacts, is broken
for apps with variants. Specifically say for a `liteDebug` app it tries to search for `.so` files inside:

```
intermediates/stripped_native_libs/lite/debug/out/lib
```

while the `.so` files are located inside:

```
intermediates/stripped_native_libs/liteDebug/out/lib
```

I've fixed changing the token of the path from `targetPath` to `variant.name`
