Handle shared UID in watchdog daemon.

- Daemon should mark a shared UID as safe-to-kill when at least one
package is marked as safe-to-kill in the config.
- Shared package names contain the "shared:" prefix and the package
specific thresholds and safe-to-kill checking are done with the prefix.
- When app cateogry is not mapped by the shared package name, fallback to
fetching app category mapped to any package under the shared UID.

Native (C++) code format is required to be compatible with .clang-format file. Run

git clang-format --style=file --extension='h,cpp,cc' HEAD~

Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
