Docker fails to build on OSX (both main and ziggy branches)

[illuzen]

Changed image line to

FROM --platform=linux/amd64 ubuntu:20.04

and change CPPLINT.cfg filter command to

filter=-legal/copyright,-build/c++11,-whitespace/indent_namespace,-build/include_what_you_use,-readability/casting

but still getting errors in the commitment scheme tests.
