* tests/file_handle.c: replace fcntl.h include with asm/unistd.h.
[MAX_HANDLE_SZ]: change to defined __NR_name_to_handle_at
&& defined __NR_open_by_handle_at, add fcntl.h include
[!MAX_HANDLE_SZ]: Add definition of MAX_HANDLE_SZ and struct
file_handle.
(main): Change name_to_handle_at and open_by_handle_at calls to syscall.
