Subject: [PATCH] [fix][ci] Fix Tune Runner VM failure when no sd* block
 devices exist

The tune-runner-vm action fails on current GitHub runner images because
the /sys/block/sd*/queue/discard_max_bytes glob no longer matches any
devices, causing tee to exit 1 and abort the job before tests run.

Sync the fix from apache/pulsar master: glob all block devices and
guard with a file-existence check.
