[PATCH v2 libevdev] Ignore -Woverride-init in event-names.h

[Peter Hutterer]

Having the declarations in the form of [0...EV_MAX] = NULL together
with the actual definitions causes warnings for every true definition if
-Woverride-init is enabled.

We can drop them for most as they're zero, but still need them for
ev_max (which defaults to -1), not zero. So use the GCC pragma to
disable the warnings for this file.

Serves me right for just copying from the server instead of double-checking
the docs. changes to v1:
- use pragma push
- pragma pop doesn't take an arg, use a comment instead
