[OE-core] [PATCH 09/45] oeqa/utils/commands: Add extra qemu failure logging

[Armin Kuster]

From: Richard Purdie <richard.purdie at linuxfoundation.org>

Rather than just referring the user to the logs containing the failure, print
them on the console. This aids debugging with oe-selftest with parallelisation
as the logs may otherwise be lost.

(From OE-Core rev: 36a018e245a232f520ff946f152cc875927a6fb4)
