crypto/internal/fips140/rsa: avoid CAST unsetting the service indicator
Without fipsApproved set, when the CAST runs it sets the service
indicator to false for the whole span.
This is a very late Go 1.24 change, but it is necessary for the frozen
FIPS module, and doesn't impact anything else than the FIPS status
indicator value.
