[OE-core] [PATCH V4 08/10] populate-volatile.sh: use 'cp -a' to avoid potential problem

[Qi.Chen at windriver.com]

From: Chen Qi <Qi.Chen at windriver.com>

Previously, dead links in target directory will not be copied.
This is incorrect as dead links are not uncommon in our rootfs.
So we use '-a' option instead.
