Fix rsync issue when maintaining data containers

**What this PR does / why we need it**:
When we stopped syncing the full .git dir into the container and created a dummy git tree, an issue arose if you're maintaining a data dir volume. The git tree created in the container wouldn't be updated if we make more commits and sync them in, and would cause a dirty tree.

This PR changes the rsync flags so that "H" filtered files are hidden from rsync on the source side, and if they exist on the destination side, they will be deleted.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes a bug introduced in #50417
