[PATCH 2/6] tests: sigma_dut: set regulatory inside try/except

If sigma_dut is not installed, start_sigma_dut() will
throw an exception. Call start_sigma_dut() inside the
try/except to correctly reset the regulatory domain.

This fixes several seemingly random failures due to
regulatory domain not being reset.
