As we already have REFFILES lazy prereq, even _before_ we enable the
reftable backend, I think that we should start t0600 and t0602 with

	. ./test-lib.sh
	if ! test_have_prereq REFFILES
	then
		skip_all='skipping reffiles specific tests'
		test_done
	fi

which is more in line with the existing convention.  It is more
efficient than "forcing t0600 and t0602 to run always with reffiles"
when you have a CI job that uses reftable for all tests and another
CI job that uses reffiles for all tests.

Presumably if there are reftable backend specific tests, they will
also be given names out of t06xx range, right?  And then they will
be skipped when the test is not using reftable as the default ref
backend, using the REFTABLE prerequisite in a similar way as shown
above for REFFILES, right?

Thanks.
