libpsl-with-scripts: init as override of libpsl

psl-make-dafsa pulls in a runtime python3 dependency which seems to have
given various build configurations no end of trouble. This solves the
problem in the least subtle manner imaginable, by removing it for all
platforms and re-adding it in a new package which currently has no
dependants. Switch your dependency from libpsl to libpsl-with-scripts
if you are impacted by this.
