Modify loader VK_ADD_DRIVER_FILES behavior

Modify the loader to only use VK_ADD_DRIVER_FILES if
VK_DRIVER_FILES or VK_ICD_FILENAMES is not used.
This could have caused weird issues with systems where VK_DRIVER_FILES
was used to force drivers in a specific order/location for testing.

Resolves issue #871
