tests::checkout: only examine test10 and test11.txt

The checkout::index::can_disable_pathspec_match test attempts to set a
path filter of `test11.txt` and `test12.txt`, but then validates that
`test10.txt` and `test11.txt` were left unmodified.  Update the test's
path filter to match the expectation.
