Split check steps in Makefile into multiple targets

This allows a `make -j4 check` invocation to actually run in parallel,
even though 95% of our test suite time is currently dominated by
pactest. It also allows running something like `make test-vercmp`.

Also, add some targets to the .PHONY list that belong in it.
