[PATCH v2] compress: resolve test failure from incomplete output capture

[Patrick Robb]

Hi David,

Because Legacy DTS is deprecated, I think you should just push Manit's
patch as is.

In the case of the Zlib test, this is a legacy DTS test which we are still
running at UNH, and we had to patch it locally to keep using the test, so
of course we felt we should push the patch to patchwork for visibility at a
minimum, and to be merged if maintainers want.

Again I don't think it is the best use of Manit's time to have him doing
further fixes in legacy DTS when he could be making other contributions to
DPDK testing efforts elsewhere. But, if you don't agree, we will adjust.
