seccomp: fix the __secure_computing() stub for !HAVE_ARCH_SECCOMP_FILTER
Depending on CONFIG_HAVE_ARCH_SECCOMP_FILTER, __secure_computing(NULL)
will crash or not. This is not consistent/safe, especially considering
that after the previous change __secure_computing(sd) is always called
with sd == NULL.
Fortunately, if CONFIG_HAVE_ARCH_SECCOMP_FILTER=n, __secure_computing()
has no callers, these architectures use secure_computing_strict(). Yet
it make sense make __secure_computing(NULL) safe in this case.
Note also that with this change we can unexport secure_computing_strict()
and change the current callers to use __secure_computing(NULL).
