Linus Walleij 81aa72e17c seccomp: Stub for !CONFIG_SECCOMP ...

[ Upstream commit f90877dd7f ]

When using !CONFIG_SECCOMP with CONFIG_GENERIC_ENTRY, the
randconfig bots found the following snag:

   kernel/entry/common.c: In function 'syscall_trace_enter':
>> kernel/entry/common.c:52:23: error: implicit declaration
   of function '__secure_computing' [-Wimplicit-function-declaration]
      52 |                 ret = __secure_computing(NULL);
         |                       ^~~~~~~~~~~~~~~~~~

Since generic entry calls __secure_computing() unconditionally,
fix this by moving the stub out of the ifdef clause for
CONFIG_HAVE_ARCH_SECCOMP_FILTER so it's always available.
