sstatesig: fix overrides behaviour to remove SIGGEN_LOCKEDSIGS_i586

Require a sig file which SIGGEN_LOCKEDSIGS_i586 is not null, but
the actual SIGGEN_LOCKEDSIGS_i586 is null.
Invoking 'bitbake -e' and we got:
...
 3935 # $SIGGEN_LOCKEDSIGS_i586 [2 operations]
 3936 #   set /path/to/locked-sigs.inc:8576
 3938 #   del data_smart.py:406 [finalize]
 3939 #     ""
...

It was caused by the following commit:

    bitbake/data_smart: Change overrides behaviour to remove expanded
      variables from the datastore
...

We add prefix 't-' to type to workaround the overrides behaviour.
