diff: allow passing NULL to diff_free_filespec_data()
Commit 3aef54e8b8 ("diff: munmap() file contents before running external diff") introduced calls to diff_free_filespec_data in run_external_diff, which may pass NULL pointers. Fix this and prevent any such bugs in the future by making `diff_free_filespec_data(NULL)` a no-op.
