chore: update the vmm-sys-util version

Update to v0.15.0 which supports sock_ctrl_msg on POSIX and adds
a cross platform event notification that uses EventFd when available
or pipe().

Because sock_ctrl_msg modifies the recv_with_fds, we need to modify the test
in vhost/src/vhost-user/connection.rs at the same time
