ci/crosvm: Retry all curl errors when downloading kernel

`--retry-connrefused` didn’t catch cases where the download started but
failed midway. `--retry-all-errors` will cover those too.

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/13800
Fixes: d527da301f ("ci: Don't include the kernel in test-base image")
