[PATCH v3 5/7] p5326: don't set core.multiPackIndex unnecessarily

When this performance test was originally written, `core.multiPackIndex`
was not the default and thus had to be enabled. But now that we have
18e449f86b (midx: enable core.multiPackIndex by default, 2020-09-25), we
no longer need this.

Drop the unnecessary setup (even though it's not hurting anything, it is
unnecessary at best and confusing at worst).
