lib/oe/rootfs: Fix DEBUGFS generation when using opkg

When enabling extra DEBUGFS image generation with opkg, errors are seen like:

ERROR: core-image-minimal-1.0-r0 do_rootfs: Cannot get the installed packages list. Command '/media/build1/poky/build/tmp/sysroots/x86_64-linux/usr/bin/opkg -f /media/build1/poky/build/tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/opkg.conf -o /media/build1/poky/build/tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/rootfs  --force_postinstall --prefer-arch-to-version   status' returned 0 and stderr:
Collected errors:
 * file_md5sum_alloc: Failed to open file /media/build1/poky/build/tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/rootfs/etc/syslog-startup.conf.busybox: No such file or directory.
 * file_md5sum_alloc: Failed to open file /media/build1/poky/build/tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/rootfs/etc/fstab: No such file or directory.

basically for all CONFFILES in the image. This is due to the file rearranging
the rootfs generation code does. If we preserve the /etc directory,
the avoids the problem.

We need to tell copyfile to preserve symlinks since some are present in /etc.
