In krb5_def_store_mkey(), mktemp was being invoked with a string WRFILE:....

This returns an error - as it actually tries to open the file.
Move some of the logic that points to the actual filename earlier - so
mktemp works on the .... portion.

Note that the netbsd linker gives a warning on using mktemp as it may be
insecure - but there is no obvious way to avoid it.

ticket: new
subhect: netbsd mktemp actually tries to open file
