Regenerate temporary passwords with null bytes

Previously, we silently cut off temporary passwords that contained a
null byte.  With the change to CString, we returned a LibraryError
instead.  With this patch, we change to generate_password function to
continue generating passwords until we have a password without a null
byte.

The chance of generating a password with a null byte is ca. 10 % for our
temporary password with 25 characters.  Therefore the chance of having
to re-generate the password multiple times is low enough that we don’t
bother with re-generating only the null bytes of the password for the
time being.  This should be improved in the future.
