package.bbclass: Fix various problems
Before this change:
a) Ownership and permissions of files copied from packages to
package-split could get lost during the copy process. This change
ensures they are preserved.
b) Ownership and permissions of directories could also get lost.
Most of the complexity in this patch is addressing this problem
ensuring newly created directories match the source ones being
copied.
c) There was no warning about directories being created but not
shipped by any package.
This patch fixes all of the above issues.
