[LTP] [PATCH] syscalls/fcntl33.c: fix test for fuse fs again

[Alexey Kodanev]

The previous fix commit 7703cb3e10ea ("syscall/fcntl33.c: fix test on FUSE
fs") moved open() (can sleep on fuse fs) before fork()/do_child(). But the
fix was removed by commit e5c990c5c55b ("Convert fcntl33 to newlib").

In this patch, instead of moving open(), use LTP checkpoints: wake the
child only after setting the lease in a parent process.
