App, cmds, lib: Fix Any returns from typed functions

Add type annotations and casts to functions that were returning Any
where a specific type was declared, satisfying the new warn_return_any
mypy rule.

Fixes:
- log.py: get_caller_pos return type via cast
- AsyncRunner.py: cast T for fut.result()
- util.py: cast for getattr result, str() for args.username
- FileContext.py: verbose_default bool annotation
- SSHClient.py: cast SSHClient for dynamic import
- lib/App.py: cast ArgumentParser, add return types to inner funcs
- pm/rpm.py, dpkg.py: cast Iterable[Package]
- App.py: cast for self.args.func(), add return types to inner funcs
- BaseCmdPkgRelations.py: cast str for args.delimiter
