[OE-core] [PATCH v2] oe/path.py: copyhardlinktree: don't overwrite existing symlinks

Before GNU tar 1.24, only the archive creation command had the '-h'
argument to preserve and follow symlinks. After >= 1.24 via commit
14efeb9f956e38d7be (tar: --dereference consistency) the capability to
preserve symlinks was also added to the archive extraction command.
-h is default at archive creation but is not default at extraction,
meaning that it will replace symlinks with directories even if the
original filesystem directory tree and archive contains them.
Add -h to the copyhardlinktree extraction step so the build can
support symlinks in variables like ${DEPLOY_DIR_IPK/RPM/DEB}.
