proposed patch

The OpenSSH with latest Fedora fails to login users because of seccomp
is killing it. This is caused by recent change in glibc and change of
implementation of nanosleep, which is affecting privsep child. For more
information, see the Fedora bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1771946

The attached patch should address this issue (I will give it some more
testing).
