wavenc: generate a non-empty data header
Restore the behavior of the element to the state before commit db29522a430e44450415ca3676abd1b77ee923d9. A non-empty header is generated and when the EOS event is received the header is generated again, this time with the correct size. https://bugzilla.gnome.org/show_bug.cgi?id=711699
