Remove python based tools (dnssec-keymgr, dnssec-coverage, dnssec-che…

With the introduction of dnssec-policy, the aforementioned tools were

based tools.  Remove the tools and the requirement to have Python
installed.  Python 3 is still being used for tests, so keep the autoconf
test, but make it much simpler.
