Rockcraft parts permissions field follows symlinks when changing ownership.

[weiiwang01]

Bug Description

When the permissions field is defined in parts, the chown operation follows the symlink. This causes issues because files are copied and chown-ed one by one. Sometimes, when a symlink is processed before its target, it results in an error.
