Rob Murray a3fdad84ad graphdriver/copy: faster copy of hard links ...

The DirCopy() function in "graphdriver/copy/copy.go" has a special case for
skip file-attribute copying when making a hard link to an already-copied
file, if "copyMode == Hardlink". Do the same for copies of hard-links in
the source filesystem.

Significantly speeds up vfs's copy of a BusyBox filesystem (which
consists mainly of hard links to a single binary), making moby's
integration tests run more quickly and more reliably in a dev container.

Fixes #46810
