[Minor] Incorporate additional bad attachments from Microsoft

These are as follows:
- htc: HTML Component File
- pyc: Compiled Python Script
- pyo: Optimized Compiled Python Module
- pyw: Python Script To Be Executed With Suppressed Terminal Window
- pyz: Python Zip Application
- pyzw: Python Zip Application
- vhd: Virtual Hard Disk
- vhdx: Virtual Hard Disk Extended
- wsf: Windows Script File

Note that the Python file types remain unscored in archives, so
distribution of these in source tarballs and the like is not affected by
this commit.
