Android build fails for AndroidTest with minSdkVersion 17 with react-native 0.64

[Merlier]

I'm using Detox for e2e tests and after upgrading to RN 0.64, the app detox build fails.
This issue could concern multiple modules. It's referenced here: wix/Detox#2712

The following command fails after upgrading to RN 0.64
./gradlew assembleDebug assembleAndroidTest -DtestBuildType=debug

With the following message:
`

Task :react-native-sha256:processDebugAndroidTestManifest FAILED

Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 21,
or use tools:overrideLibrary="com.facebook.react" to force usage (may lead to runtime failures)

I looked for several solutions but the easiest would be to update the gradle android config of react-native-sha256, inspired from other gradle file of module like: https://github.com/react-native-async-storage/async-storage/blob/master/android/build.gradle
