Fix assertion failure in Unix PuTTYgen exports.

Browse Source 
The assertions I added to sshrand.c in r9930 are now justified,
because they were failing when cmdgen was used to convert a key into
either foreign private key file format - both the export functions
require random_byte() for one reason or another, and random_ref()
hadn't been called first.

[originally from svn r10117]
