[PATCH 2/2] t5302: confirm that large packs mention limit

["Matt Cooper via GitGitGadget" <gitgitgadget@gmail.com>]

From: Matt Cooper <vtbassmatt@gmail.com>

When a pack can't be processed because it's too large, we report the
exact nature of the breach. This test ensures that the error message has
a human-readable size included.
