vndk-def: check-dep: Print symbols and module_path

This commit add the functionality to print depended symbols from
ineligible libs and violating module source path to check-dep
subcommand.

Test: ./tests/run.py

Test: Run `vndk_definition_tool.py deps --symbols` on various tree and
the output should remain identical.

Test: Run `vndk_definition_tool.py check-dep --module-info ...`

Bug: 32811412
