Run script/test quietly with coverage, rerun failed tests verbosely (closes #315)

script/test now runs the suite once with -race -cover and no -v. On a failure it reruns only the failed top-level tests, with -v, in the packages that failed, then exits non-zero whatever the rerun shows. A green run stays quiet, and a red one ends with the failing tests' verbose output, which the Docker build's 2 MiB log limit can hold; a verbose rerun of every package would pass that limit again. A failure that names no test (a build error, a timeout) skips the rerun, since the quiet run already prints that package's output. The timeout and parallelism are unchanged.
