t1092: refactor 'sparse-index contents' test

Browse source 
Before expanding this test with more involved cases, first extract the
repeated logic into a new test_sparse_checkout_set helper. This helper
checks that 'git sparse-checkout set ...' succeeds and then verifies
that certain directories have sparse directory entries in the sparse
index. It also verifies that the in-cone directories are _not_ sparse
directory entries in the sparse index.
