Subject: [PATCH] Suppress manykeys test on duplicate key ids

If there are duplicate key ids across multiple algorithms expected
output is no met.  We have fixed this in on main but decided to not
back port the fix as it will change the statistics channel output.

This change detects when there are duplicate key id across algorithms
as skips the sub test.

(cherry picked from commit ea1d3476a8b0c8a582b80a1bfdffa614bb553ab6)
