From: Alexander Kanavin <alex@linutronix.de>

This is already performed in eSDK creation; the change allows also
making a copy with a standalone 'bitbake -S unihash-cache-copy targets...'
command, which is useful for replicating builds on a different build host
(simply coping sstate objects is not enough if they need to be discovered
through unihash redirections).
