Always report FIPS mode true on developer platforms (#1177)

The OpenJCEPlusFIPS provider may run on platforms that support developer
mode. On these systems, the provider should always report that it is operating in FIPS mode
to ensure behavior is consistent with fully FIPS-certified platforms.
This change simulates FIPS operation as closely as possible in development environments.
