oe.path: preserve xattr in copytree() and copyhardlinktree()
Pass appropriate options to tar invocations in copytree() and
copyhardlinktree() to ensure that any extended attributes on the files
are preserved during the copy.
We have to drop the use cpio in "Copy-pass" mode in copyhardlinktree()
because cpio doesn't support extended attributes on files. Instead we
revert back to using cp with different patterns depending on whether
or not the directory contains dot files.
