LOG: [llvm-exegesis] Allow retries on flaky middle half test

The middle half repetition mode test sometimes fails on the avx512
buildbots due to a negative value being produced. This needs more
investigation, but add a retry count temporarily to alleviate
false-positive errors on the buildbots.

This is being tracked in #80957.
