criu/files: Fix wait_fds_event() for 64 bit platforms

Browse source 
The htole64() function returns a 64 bit value. This is stored in
a 32 bit integer in wait_fds_event() which results in 0 for big-endian
64 bit platforms. The fuxtex() system call also requires 32 bit values.

Fix this and use htole32() also for 64 bit platforms.
