Don't set xtrace directly in local call
Ia0957b47187c3dcadd46154b17022c4213781112 detects setting local variables with subshell commands. Although this is a particuarly benign case, it trips the test. Rather than putting in an ignore for this, we can easily change it to make the test pass. This seems better than putting in special work-arounds to bashate, etc. Change-Id: I37c3967c0f2d780a636a7d26cda83755085c5c69
