IMPALA-7442: reduce mem requirement of semi-joins-exhaustive

The test started running into IMPALA-7446, maybe because of
a timing change. This appears to have always been possible.

The fix is to reduce the memory requirement of the test.
IMPALA-2256 is no longer really possible because the
BufferedTupleStream code was simplified to avoid the 32-bit
row index limitation, so we're not losing important coverage
on the current code with this change.

Testing:
Ran test in a loop to confirm it did not OOM.
