ci: extracting files in scaling test takes too much time

[BugenZhao]

Before #8326, on "scaling test (deterministic simulation)":

�_bk;t=1678035269235��[32;1m   Extracted�[0m �[1m63�[0m files to �[1m/tmp/nextest-archive-oA0Tga�[0m in 7.60s

After it:

2023-03-06 12:00:11 UTC | Extracted 63 files to /tmp/nextest-archive-0zQhiA in 7m 36.09s

Not sure whether it's related to the debug-info... 😟 cc @fuyufjh Seems not relevant. ci-sim is based on dev profile and the artifacts are not built with build.sh.

@liurenjie1024 has increased the timeout time on main, if it is a bug, we need to change it back after we fix it. #8409

[BugenZhao]

I believe it's a bug.

cc @xxchan @wangrunji0408 🥺

Can't reproduce locally.

I got the reason. It's because every time cargo nextest run --archive-file extracts the archive once. When parallel, it OOMs, so it's naturally slow.
