As a side effect, this also fixes a minor memory leak. On function return, "g_auto(GStrv) argv" frees argv and each element, which is wrong, because the function does not own the individual elements. To compensate, the code uses g_steal_pointer which NULLs argv and prevents the destructor from running, but argv is leaked. Fixes: cbab4face57b ("migration: convert exec backend ...")
