Subject: [PATCH] test(buzz-acp): quote the steer capture path for bash

The capture path was interpolated unquoted into a bash -c script, so on Windows
bash ate the backslashes as escapes: the redirect wrote a mangled relative file
into the crate directory and both steer tests failed on the missing capture.
Render with forward slashes and quote the redirect target.
