selftests/exec: check that a binfmt_misc instance cannot be pinned
An 'F' entry whose interpreter keeps the binfmt_misc superblock alive
pins the instance that owns it forever. Cover both ways to build that:

- an interpreter on the instance's own files, control file and entry
  file alike

- and an instance used as an overlayfs lower layer.

Check that an ordinary 'F' registration still succeeds so the fix stays
honest about not changing what 'F' promises.
