Secure Boot: Support Independent signing mode in genPnorImages.pl

This changes signMode() from a tuple to a triple, supporting 'independent'
as an allowable value, and passing this value to crtSignedContaner.sh as
appropriate.  For simplicity, Independent mode is not considered in the
setting of the LAB_SECURITY_OVERRIDE_FLAG or for transition containers.
