merge: improve working-copy mtime race handling

Explanations inline. This also makes use of `make_mtime_reliable`, which
unifies our mtime raciness logic from the status.

On top of this, this fixes the handling of the pure dirstate status to better
catch racy status, as we've been doing in Rust for a long time now.
