tmpfiles: Don't fail if file does not exist in item_do()

If the file was removed by some other program, we should just go
to the next one without failing. item_do() is only used for recursive
globs instead of fixed paths so skipping on missing files makes sense
(unlike if the path was fixed where we should probably fail).

Fixes #32691 (hopefully)
