`./x test bootstrap` shows curl progress bars

[Teapot4195]

Steps to reproduce

1. clear the files under build/cache/[date] for those that aren't for your host triple.
2. clear the folders under build that isn't for your host triple. (e.g. aarch64-apple-darwin if building on x86-64-windows-msvc)
3. run ./x test bootstrap
4. observe under a block of 37 tests, the curl progress bar shows up 6 times.

Ideal solution

• When building the command for curl, possibly suppress the progress bar with -s in tests.
• Possibly don't download for those targets in the first place?
  • The tools being downloaded appear to be native (not cross), I can't really see a use given they can't run on a mismatched host triple.

If someone happens to know where these curl commands are being called from, that would be helpful :)

For whoever picks up this issue: I can't exactly mentor this issue but if you do need help, feel free to ping me on zulip.

Labeled easy since it doesn't look that difficult to fix.
