commit 1826a8cb8cf4c51307003617864d2ffab273eb0b
Author: Richard Purdie <richard.purdie at linuxfoundation.org>

    oeqa/runqemu: Only show stdout/stderr upon test failure
    
    In general we don't need to see the output of runqemu however if it fails
    we do. Use the buffer option that already exists in TestResult but allow
    us to trigger it on a per test basis.
