Ignore -Woverride-init in event-names.h

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.
