Remove nonexisting folder from include path

[maxgerhardt]

Description of Change

The PlatformIO builder scripts attempt to include tools/sdk/esp32/include/config to the include path (and similiarly for the other MCU types), but this folder does not exist anymore.

VSCode emits a "Problem" warning for non-existing folders declared in the therefrom created .vscode/c_cpp_properties.json.

The fix trivially removes these folders from the include path. If the include/config folder was renamed and is not yet in the PlatformIO builder script, let me know.

Tests scenarios

Tested with PlatformIO using

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
platform_packages = 
   framework-arduinoespressif32@https://github.com/maxgerhardt/arduino-esp32.git#patch-2

and the "Problems" view cleared out.

This actually needs fixing in the lib-builder

OK. Thanks :) Merging here and already fixed in the lib-builder for the future.
