redhat/configs: change ipv6 from builtin to a module and disable FIPS for automotive

Brian Masney requested to merge bmasney/centos-stream-9:disable-fips-ipv6-mod into main-automotive

Upstream Status: RHEL Only

JIRA: https://issues.redhat.com/browse/RHEL-2363

To help with the overall automotive kernel boot speed, make the following two Kconfig changes:

  • Change ipv6 from a built in to a module since this knocks ~170ms off the overall boot speed.
  • Disable FIPS and the crypto self tests on bootup since this knocks an additional ~200ms off the overall boot speed.

Note that changing ipv6 from a built in to a module disables some functionality that's described in the commit message.

Note that this change is going to cause some BPF tests to fail, and mptcp tests to fail as well. Those tests will need to be excluded from the test suite for automotive.
