[PATCH] selftests/kselftest/runner.sh: Add 30 second timeout per test

[Anders Roxell <anders.roxell@linaro.org>]

Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per
test") solves that binary tests doesn't hang forever. However, scripts
can still hang forever, this adds an timeout to each test script run. This
assumes that an individual test doesn't take longer than 30 seconds.
