Improve build/updater

* Fix `get_executable_path` in UNIX
* Update `x86.exe` correctly
* Exit immediately in windows once the update process starts so that the file handle is released correctly
* Show `exe`/`zip`/`source` and 32/64bit in verbose message
* Look for both `yt-dlp` and `youtube-dlc` in releases. This ensures that the updater will keep working when the binary name is changed to yt-dlp
* Disable pycryptodome in win_x86 since it causes `distutils.errors.DistutilsPlatformError: Microsoft Visual C++ 10.0 is required`
