[PATCH] tests: check for hwsim before loading it

From: Johannes Berg <[email protected]>

Instead of checking if the kernel allows modules (via the
presence of /proc/modules), check if hwsim is already there
and load it only if not. This gets rid of some ugly prints
from modprobe in case code isn't even a module and cannot
be found, etc.
