is_wireless_device: fix UUoC and reorder
There's no need to $(cat .../uevent | grep DEVTYPE) and then compare it to what we're looking for. grep can do all of it for us ("Useless Use of Cat"). While at it, if we have three ways of checking whether a device is wireless, let's order them from least expensive (checking dir is only one stat()) to most expensive (iwconfig | grep). Proof of correctness: if "iwconfig | grep" is returning true and the other two methods are not, we will still reach "iwconfig | grep" in the series of if/elif.
