Makes Makefile use the $(CP) makro instead of $(INSTALL_BIN) for "library"-functions shell scripts.

As '/lib/netifd/hostapd.sh' and '/lib/wifi/mac80211.sh' should never be
called directly (but only be included from other files like '/lib/netifd/
wireless/mac80211.sh', these files do not need to have an execute bit
set, which on the other hand would be ensured by using the
$(INSTALL_BIN) macro in the make file. The $(CP) macro would simply copy
the files from the package into the image and preserve their
permissions.
