Subject: [PATCH] build: Fix DRI3 on DragonFly and OpenBSD

Commit 96bdc156 added a check for <sys/eventfd.h> to enable DRI3.

DragonFly and OpenBSD however rely on epoll-shim for <sys/eventfd.h>,
so that must be added as a dependency for the <sys/eventfd.h> check.

Fixes: commit 96bdc156 - xwayland: Do not enable DRI3 without eventfd
