When we have updated kernel headers to 5.2-rc1 we have introduced
new syscall numbers that can be not supported by older kernels
and fail with ENOSYS while the guest emulation succeeded before
because the syscalls were emulated with ipc().
This patch fixes the problem by using ipc() if the new syscall
returns ENOSYS.
Fixes: 86e636951ddc ("linux-user: fix __NR_semtimedop undeclared error")
