[OE-core] [PATCH 06/11] oeqa/targetcontrol: write QemuRunner log output to a file

[Paul Eggleton]

If we use this outside of testimage we don't have a task log; so let's
just explicitly write the log output to a file all the time so it's
always there to look at (particularly useful when runqemu exits
immediately with an error.)
