manifestmerge: handle abort on local unknown, remote created files

This replaces the _checkunknown call in calculateupdates with a more
performant version. On a repository with over 150,000 files, this speeds up an
update by 0.6-0.8 seconds, which is up to 25%.

This does not introduce any UI changes. There is existing test coverage for
every case, mostly in test-merge*.t.
