test-fs-largefile was disabled. It was fixed inbbf74fbbut left in disabled because it generates a 5Gb file. However, gibfahn had the sensible suggestion of moving it to the pummel directory. Which is what this change does. In pummel, lint rules are applied, so this does necessitate changing a pair of `var` declarations to `const`.
