[compat-wireless] modprobe -l is legacy compatibility mode and is being removed from some distros

[Richard Farina <sidhayn@gmail.com>]

module-init-tools has been deprecated in favor of kmod in Arch Linux, 
and kmod doesn't have the legacy --list option for modprobe.
This patch fixes the areas of the Makefile which actually needed the 
output of modprobe -l. The other 100's of uses are just to echo info to 
the screen which in this case will simply fail in an extremely noisy 
fashion yet non-fatal way.

Please apply to all branches.
