[PATCH v2] passt: Rename EPOLL_EVENTS to NUM_EPOLL_EVENTS

[Laurent Vivier <lvivier@redhat.com>]

The macro EPOLL_EVENTS conflicts with enum EPOLL_EVENTS defined in
sys/epoll.h (glibc).

Rename the local macro to NUM_EPOLL_EVENTS to avoid this namespace
collision.

Notes:
    v2: Rename PASST_EPOLL_EVENTS to NUM_EPOLL_EVENTS for better clarity
