A few minor changes to the existing roachtest:

Reduce the warehouse count on ingest back to 100 - this should be ample,
and it matches the warehouse count on the read path in a later part of
the test.

Change the stop options to wait until the process has been terminated
before continuing.

Re-work the command to search for SSTables to corrupt - use tables from
the most recent manifest (if multiple are present); consider SSTables
with either a start or end key representing a user table; shuffle tables
to distribute corruption over the LSM; perform filtering in the bash
command rather than in the test runner itself.

Release justification: Roachtest-only change.

Release note: None.

Touches #77321.

I also did a stress test of this, and it came back clean. That's not to say this fixes whatever is causing #77321, just that the test still works as expected.

I walk back the comment about the stress test not failing. I ran it again and hit what seems to be #77627. That's unrelated to the changes, but thought I'd mention it.
