[POWERPC] Fix PPC32 SECCOMP, unexport do_syscall_trace_{enter,leave}
The secure_computing() call which automatically aborts a process if it tries to execute a syscall it shouldn't is much more useful if we actually do it _before_ the syscall, rather than afterwards. PPC64 got this right, but the original incorrect behaviour inherited from arch/ppc was preserved by ifdefs. Make it the same on PPC32 too. Also, I see no need to export do_syscall_trace_{leave,enter} on ppc32 -- they were only exported because the old do_syscall_trace() (which they replaced) used to be.
