    Fix copyright, remove "all rights reserved".
    
    The eventfd code was written by me, rdivacky@ copyrigth applicable only
    to epoll part of the Linuxulator code. Roman is ok to retire his copyright
    from sys/kern/sys_eventfd.c and 'All rights reserved.' lines from
    sys/compat/linux/linux_event.[c|h] and sys/kern/sys_eventfd.c files.
