Subject: [PATCH] nbis: Add a global include file with all the definitions
 ignoring erros

The nbis headers are full of redundant declarations, we can't fix them all
now, so in the mean time let's use an header using pragma to ignore such
errors.

Add the error to nbis private include folder that should be used only by
headers of libfprint-nbis.
