As noticed in https://bugzilla.redhat.com/show_bug.cgi?id=2239008#c16, when compiling a kernel as a user and doing 'sudo make install', and when using a non-vfat fs for the install destination, the file would end up owned by the user. This is not useful at all, so let's only preserve the timestamps on the copied file, no other attributes. Signed-off-by: Zbigniew Jędrzejewski-Szmek <zbyszek@in.waw.pl>
