hnbgw: Fix regression in hnbgw-test-latest

Fix unintended if condition removal in recent commit when
in the -latest case. That commit expected to leave the -latest path
untouched but ended up removing the line. Re-add it.

Print load before and after each test

Make it easier to figure out why tests are failing sporadically by
printing the load before and after each test. For example:

------ MGCP_Test.TC_crcx_sdp ------
(14:24:42) load average: 0,41, 0,44, 0,54
