[PLAT-10806] Searching custom path for active software

Summary: Issue with replicated to YBA-installer migration where searching for the version failed because we had a custom install root and we had previously hardcoded /opt/yugabyte. This diff uses the argument data_dir (which in the YBA-installer case is the BaseInstall/installRoot) when finding the realpath of the active directory.

Test Plan: Run backup/restore with custom install root.
