oeqa: add output to subprocess exceptions
Out of the box subprocess.CalledProcessError.__str__() just displays the command and exit code, which isn't very useful for debugging. Add a function to oeqa.utils.subprocesstweak to monkey-patch __str__() so that it can also display the value of stdout and stderr. (From OE-Core rev: c55401ba1646202fa36e4973b05dbacaa146cb16) Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
