[Bug 1856753] [NEW] python 2.7.17-1~18.04 causes ImportError in ujson.so

Public bug reported:

With python 2.7.17, ujson==1.35 does not install from PyPI properly.
This was not a problem with 2.7.15-4ubuntu4~18.04.2.

The root cause is likely during the `bdist_wheel` operation, as a whl
built with python 2.7.15 will install and function under 2.7.17.

Steps to reproduce are as follows; I have been reproducing this in the
ubuntu/bionic Docker container:

 apt-get update && apt-get -y install python-pip python2.7-dev
 pip install ujson
 python -c "import ujson"

The resulting error is:

 ImportError: /usr/local/lib/python2.7/dist-packages/ujson.so: undefined
symbol: Buffer_AppendShortHexUnchecked

A diff of dpkg-query -W between working and failing containers follows.
(this is from the full environment, not the MCVE above -- therefore
unrelated packages are shown in the diff).
