[PATCH libevdev 3/4] Blacklist SW_MAX so it doesn't shadow SW_PEN_INSERTED

[Peter Hutterer]

They have the same value, so the _MAX code would shadow the real code, causing
issues in any client that needs to get all event names from libevdev.
Specifically, the loop of:
  for each code in 0 to max-for-type:
      print(name)
would not show up the code (but the _MAX) code instead. This causes issues
with clients that rely on name resolution that works. And the _MAX values are
special values anyway.

Blacklist it in the script here, causing it to resolve from name to code, but
not from code to name (like other duplicated codes).
