[PATCH 1/2] arm/trusted-services: upgrade in-tree nanopb

Trusted Services uses nanopb 0.4.8 but this imports pkg_resources from
setuptools, which has been deprecated since 2023[1] and was finally
removed in setuptools 82.

This was fixed in nanopb some time ago[2] so upgrade the recipe from
nanopb 0.48 to 0.49.1.
