You've got a terminology problem here.  You're trying to start the
*sshd* service, and sshd is giving you these errors.  The fact that
cygrunsrv is the generic framework used to run any Cygwin daemon as a
service does not mean this has anything to do with cygrunsrv per se. 
The errors are from sshd.

These are indicative of incorrect permissions on those files.  Did you
run ssh-host-config?  Did you ever mess around with running sshd as a
non-service?  If yes, then that creates these files with incorrect
permissions.  In any case, delete them and re-run ssh-host-config and
they should be created with the proper owner/mode.

Existance is not sufficient.  The ssh daemon requires them to be secured
otherwise it won't start, since having them readable by untrusted users
would compromise the security of the daemon.
