small fix to restore local multiplayer on evdev

[toccata10]

All credit goes to @Megamouse . There's a big #3817, but it might take some time before it's ready.
Since the nice gui configuration, only one evdev gamepad is usable on master. So, it's a regression.
I believe it would be very nice to restore the local multiplayer ability on Linux (without waiting for the #3817).
It's a very small fix.
Maybe @Megamouse wants to push this under his own name ?

I already pushed it.
but someone:tm: hasn't had time to reviiew yet xD

Sorry, I couldn't find it in the waiting queue. I see it's in the #3817 and it fixes the multiplayer, but the #3817 also breaks the compatibility with custom sticks (no left direction for example, for me) in evdev, so I think it's not in a mergeable state yet (and it could take a little while to be ready).
My idea was to just fix this in the meantime (because it's really cool to be able to play with a friend on the latest master (without recompiling)). But if you think it's best to wait for a correct #3817, just let me know.

[Megamouse]

not at all. i don't care what's merged first.

the thing is that evdev is pretty much broken anyway for certain dumb controllers until the workaround (for example dedicated trigger-list) is implemented.

Current master is the real broken code. it's just wrong how I checked for triggers in the first place.
and the original implementation was even worse.

OK, so let's hope someone merges this: it'll make Linux users happy.

[Megamouse]

should be obsolete now that 3817 is merged

[toccata10]

Yes. Closing this.
