Move FIPS mode config option to SSLModConfigRec since it is a global
SSL library setting.  Additionally, always log the FIPS mode since it
can be set outside of the httpd config.

* modules/ssl/ssl_private.h (SSLModConfigRec): Move fips field here.
  (SSLSrvConfigRec): ... from here.

* modules/ssl/ssl_engine_config.c (ssl_cmd_SSLFIPS): Adjust for fips
  field move.

* modules/ssl/ssl_engine_init.c (ssl_init_Module): Adjust for fips
  field move.  Always log the OpenSSL FIPS mode state even if SSLFIPS
  is not used.
