Blacklist REP_MAX so it doesn't shadow REP_PERIOD

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.
