fix(tbbr): unrecognised 'tos-fw-key-cert' option

CCA CoT uses 'core-swd-cert' for signing all secure software, so when
using cert_create tool to generate its certificate, it throws an
error:  "tools/cert_create/cert_create: unrecognized option
'--tos-fw-key-cert'".
The issue has not been seen so far since "SPM+RME+TBB+Measured-Boot"
combination is not tested in CI/local-setup. It is now resolved by
guarding usage of '--tos-fw-key-cert' for non-CCA CoTs.
