largefiles: confirm existence of outgoing largefile entities in remote store

Before this patch, "hg summary" and "hg outgoing" show and count up
all largefiles changed/added in outgoing revisions, even though some
of them are already uploaded into remote store.

This patch confirms existence of outgoing largefile entities in remote
store, to show and count up only really outgoing largefile entities at
"hg summary" and "hg outgoing".
