tests: avoid unnecessarily looking inside .hg/ in test-narrow*
Many of the narrow tests were looking at .hg/narrowspec. I think most
of them were written before we added `hg tracked`, but now that we
have that command, we should fix the tests. There were also a few
instances of tests looking at .hg/dirstate. I fixed those to use `hg
files` instead.
