[PATCH] archiver: Don't try to preserve all attributes when copying files

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Similar to https://git.openembedded.org/bitbake/commit/?id=2f35dac0c821ab231459922ed98e1b2cc599ca9a
there is a problem in this code when copying from an NFS mount.

We currently use cp -p, which is a shortcut for --preserve=mode,ownership,timestamps.
We shouldn't need to preserve mode/ownership, only timestamps. Update the code
in the same way the bitbake fetcher was fixed for consistency.

This fixes build failures on OpenSUSE 16.0.
