Rebase FIPS patches from fips branch and simplify by using a single patch from that repository
    
    * RH2051605: Detect NSS at Runtime for FIPS detection
    * RH2036462: sun.security.pkcs11.wrapper.PKCS11.getInstance breakage
    * RH2090378: Revert to disabling system security properties and FIPS mode support together
    
    Turn off build-time NSS linking and go back to an explicit Requires on NSS
    Rebase RH1648249 nss.cfg patch so it applies after the FIPS patch
    Perform configuration changes (e.g. nss.cfg, nss.fips.cfg, tzdb.dat) in installjdk
    Enable system security properties in the RPM (now disabled by default in the FIPS repo)
    Improve security properties test to check both enabled and disabled behaviour
    Run security properties test with property debugging on
    Exclude x86 from builds as the bootstrap JDK is now completely broken and unusable
