[PATCH 11/12] t/helper/test-pack-deltas: widen `do_compress()`'s maxsize local to `size_t`

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

Prep for the upcoming `git_deflate_bound()` widening to `size_t`. The
local is only ever the return value of `git_deflate_bound()` and the
`xmalloc()`/`stream.avail_out` sizes derived from it; widening it has no
semantic effect today.
