[core] try to fix android instrumented test building error (#19447)

# Why

multiple libc++_shared.so build errors from android instrumented test: https://github.com/expo/expo/actions/runs/3202259013/jobs/5231059790

# How

- always exclude libc++_shared.so from packaging.
- this pr also removes the previous change from #19254, we don't have to exclude META-INF files. [they are excluded by default](https://android.googlesource.com/platform/tools/base/+/mirror-goog-studio-main/build-system/gradle-core/src/main/java/com/android/build/gradle/internal/packaging/PackagingOptionsUtils.kt#20). the reason we need to do it because the `excludes = []` reset all list. replace the statement by `excludes += [...]` is better than this.

# Test Plan

- android instrumented test ci passed: https://github.com/expo/expo/actions/runs/3203065701/jobs/5232723291
- all ci passed (updates e2e seems broken on main)
- check regression from #19254 by running `yarn e2e` locally in expo-dev-client
