0c938550cf Update probing in membarrier_test 
Updates HasMembarrier(cmd) to probe rather than execute command to fix
unintended test skipping.

Test: manual on OrangePi Zero running 4.17.4.

795034cab8 Fix membarrier test. 
Some older kernels do not support all membarrier commands. For example,
the 4.9.x kernel only supports MEMBARRIER_CMD_QUERY and MEMBARRIER_CMD_SHARED.

Test: Ran unit tests on hikey.
