Gunnar Beutner dff8b3d2d9 Meta: Make rsync a hard dependency and remove the fallback code
Previously we'd fall back to using cp if rsync wasn't available. Not
only is this considerably slower it also breaks when some of the files
in the target directory are symlinks because cp tries to dereference
them.

Fixes #8672.
