Subject: [PATCH] 95ssh-client: attempt to copy UserKnownHostsFile to kdump's
 initramfs

Bug related to this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1360131
Now dracut only attempts to copy GlobalKnownHostsFile while generating kdump's
initramfs. This method will cause kdump's failure if users set customized
UserKnownHostsFile in /etc/ssh/ssh_config. This patch simply attempts to copy
those files too while going through /etc/ssh/ssh_config. Note that we need to
make sure ~/foo will be copied as /root/foo in kdump's initramfs.
