use 2.7 get-pip.py to install pip 20.3.4 to run on python2.7 #414

because pip 21.0 is released, which dropped python 2.7 support in january 2021. https://pip.pypa.io/en/latest/development/release-process/#python-2-support

with https://bootstrap.pypa.io/2.7/get-pip.py, we can install pip 20.3.4, which supports python 2.7.

Thank you. I think this will not pass on testing, because it uses default branch.
