[Buildroot] [PATCH 1/1] package/python-ujson: needs python3

[Fabrice Fontaine]

python 2 support has been dropped since version 3.0.0 and
https://github.com/ultrajson/ultrajson/commit/0673d237cf5589a2a059771f694d5fbc5a293b13
resulting in the following build failure since bump to version 4.1.0 in
commit a47f332a20bf3f79ef4903c8ddd2b7917217e354:

  File "setup.py", line 37, in <module>
    with open("README.rst", encoding="utf-8") as f:
TypeError: 'encoding' is an invalid keyword argument for this function

Fixes:
