Subject: [PATCH] Disable FIPS options

On RHEL, FIPS should be configured only on system level.
Additionally, the related options may cause segfault when used on RHEL.

This patch causes the option processing to end sooner
than the problematic code gets executed.
Additionally, the JS-level options to mess with FIPS settings
are similarly disabled.
