[packages] net/ipkungfu: Cleanup

- use openwrt locations for utilities, fixes compilation on systems missing those utilites, allows ipkungfu to run
 - $(INSTALL_BIN) to properly install binaries
 - rewrite to use insmod in place of modprobe
 - depends on bash
 - delete autogenerated md5sum manifsts during removal, fixes reinstallation/upgrades
 - needs more work, but this is a start and prevents error during compilation
