[CRIU] [PATCH 02/10] eventfd: Add checkpoint/restore support v2

[Cyrill Gorcunov]

v2:
 - Pass initial counter value to eventfd call
   (can't pass flags here since they are obtained
    with fcntl and must be restored same way or
    restore will fail)
 - Use rst_file_params for flags and owner restore
 - Use eventfd.[ch] instead of eventfs.[ch]
 - Move show funcs to eventfd.c
