core: Ensure glib standard::size attribute is always set

* A recent change in glib [1] requires that the appropriate attribute
be available when calling getters. ostree core only sets this attribute
on regular files, and frequently triggers the critical warning. Solve
this by setting standard::size to zero for non-regular files.

Fixes https://github.com/ostreedev/ostree/issues/2827
