[PATCH] test: py: add xfail test for surprising hush quoting behavior

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

When mixing both double quotes and single quotes in a command and
passing it through labgrid, the quoting labgrid does on top will exceed
barebox hush's abilities. Fixing this is likely an involved matter, but
let's add a test that's expected to fail, so this can be revisited in
the future.
