snort: fix epoll_wait unsigned return value

When epoll_wait return -1, access array epoll_events[i] out of bound and lead to segmentation fault. 1. Change return value to signed return value 2. Skip non fatal error e.g. EINTR Type: fix Signed-off-by: Tianyu Li <tianyu.li@arm.com> Change-Id: I4ece118999402ec6054baf0efb52419151655def
