data/projectconfig.yaml: Remove %{fix-pyc-timestamps}

Removing this because:

  o Newer versions of python don't use timestamps in pyc files anymore
  o No references in buildstream core refer to this variable anymore
  o We don't have an ICLA on file for the original contribution of this

We can safely add this to external python related element implementations
if it is needed.

This closes issue #1409
