[LV] Restore metadata to disable runtime unrolling for epilogue loop.

After d4a8fc3a87a1 LV stopped adding metadata to disable runtime
unrolling to the vectorized epilogue loop. This was missed because
278aa65cc495 removed the relevant test coverage.

This patch fixes that by adding the relevant metadata after
vector loop generation.
