Move conformance tests to tests directory (nginx#1969)

Problem: The conformance directory is outside our tests directory containing all our tests. This conformance directory has a separate Makefile with many duplicated commands and variables.
At release time we have to update all the versions in multiple places.

Solution: Move the conformance tests inside the tests directory and consolidate the Makefile so it's easier to maintain and update at release time
