#1455851 — [PATCH 03/10] fault injection: allow FAULT_INJECTION_STACKTRACE_FILTER on X86_64

This config option was apparently disallowed on x86_64 because of
problems with the stack unwinder:

        fault injection: disable stacktrace filter for x86-64

However, I observe no problems whatsoever with this today and in fact
it's been very useful for debugging. Let's allow it again.
