rpm: Update CellServDB

rpm: Update CellServDB

The commit (a5d66d05fa0308d505de8bde59442e29be9d04f8) which updated
our in-tree copies of the CellServDB for the 14th August release
failed to update the copy that's referenced from the rpm spec file.
Update the filename used here so that rpms also get to have an
up to date CellServDB
