Preserve owner approvals for rebase-only file changes

The owners plugin currently removes approvals guarded by
approverin:already-approved-by_owners whenever the newest patch set
modifies files owned by the approver.

This also happens when the apparent modifications are caused solely by a
rebase, where file content shifts due to base movement rather than
manual edits by the uploader. In these cases, the owner has already
reviewed the effective change, yet is forced to re-approve
unnecessarily.

Extend the already-approved-by_owners predicate so that owned files
modified only by rebase operations are treated as unchanged. Rebase-only
diff hunks, no longer cause owner approvals to be cleared.

This preserves owner approvals across rebase-only patch sets while still
clearing them when genuine content changes are introduced.
