u-boot-qoriq: add 'python3-setuptools-native' to depends

Building this recipe on an Unbuntu 20.04 host results in the following
error:

    Traceback (most recent call last):
      File "u-boot-qoriq/2021.04+fslgit-r0/git/tools/binman/binman", line 39, in <module>
        from binman import control
      File "u-boot-qoriq/2021.04+fslgit-r0/git/tools/binman/../binman/control.py", line 11, in <module>
        import pkg_resources
    ModuleNotFoundError: No module named 'pkg_resources'

With the added dependency the build completes.
