The old copy-up implementation was very unhappy with symlinks, which could cause containers to fail to start for unclear reasons when a directory we wanted to copy-up contained one. Rewrite to use the Buildah Copier, which is more recent and should be both safer and less likely to blow up over links. At the same time, fix a deadlock in copy-up for volumes requiring mounting - the Mountpoint() function tried to take the already-acquired volume lock.
