[PATCH] test: Add setuptools to test requirements.txt

[Javier Tia]

It solves the following error:

❯ ./test/py/test.py --bd sandbox --build
+make O=/u-boot/build-sandbox -s sandbox_defconfig
+make O=/u-boot/build-sandbox -s -j32
Traceback (most recent call last):
  File "/u-boot/build-sandbox/../scripts/dtc/pylibfdt/setup.py", line 23, in <module>
    from setuptools import setup, Extension
ModuleNotFoundError: No module named 'setuptools
