[PATCH 2/5] test/py: Handle u-boot-test-getrole failure

[Simon Glass]

This script can fail if there is no toolchain available for the board.
At present this is not handled very nicely, in that only the error
output is reported. It is much more useful to see everything, so
combine stdout and stderr and report them both.
