Make FIPS related options and functionality always awailable.

There is no reason to hide FIPS functionality behind build flags.
OpenSSL always provide the information about FIPS availability via
`FIPS_mode()` function.

This makes the user experience more consistent, because the OpenSSL
library is always queried and the `crypto.getFips()` always returns
OpenSSL settings.
