HID: apple: Bring back flag for Apple tilde key quirk

Browse Source 
Some Apple ISO keyboards have a quirk where the backtick/tilde key is
swapped with the less-than/greater-than key. Unfortunately, there is no
perfectly reliable way to detect whether a keyboard has the quirk or
not, but the quirk appears to only be present on models that support
Bluetooth, and the affected keyboards usually report country code 13 in
the HID descriptor.

Therefore, the best we can do is to change
/sys/module/hid_apple/parameters/iso_layout to a ternary:

0 = Not ISO or ISO and not quirky
1 = ISO and quirky
-1 = Guess based on product ID and country code

Table of keyboards that José, Julian and I have tested:
