    Yield paths to all the files in RECORD. For each .py file in RECORD, add
    the .pyc and .pyo in the same directory.

    UninstallPathSet.add() takes care of the __pycache__ .py[co].

    If RECORD is not found, raises UninstallationError,
    with possible information from the INSTALLER file.
