[12.5.X] Fix testNoParentDictionary to properly copy the package from release area

[smuzaffar]

backport of #39367

In patch release we could have symlinks src/SubSystem/Package pointing to FULL_RELEASE/src/SubSystem/Package . This can cause the unit test testNoParentDictionary.sh to fail. This change now properly copies the package DataFormats/TestObjects from patch release by dereferencing the symlink

please test

This pull request is fully signed and it will be integrated in one of the next CMSSW_12_5_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_6_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
