[PATCH - linux-next] ARM: ptrace: Fix audit caused compile error

[Peter Ujfalusi <peter.ujfalusi@ti.com>]

While trying to compile the kernel for ARM (omap2plus_defconfig) the kernel
build fails with:

arch/arm/kernel/ptrace.c: In function ‘syscall_trace’:
arch/arm/kernel/ptrace.c:920:3: error: implicit declaration of function ‘audit_syscall_exit’
arch/arm/kernel/ptrace.c:922:3: error: implicit declaration of function ‘audit_syscall_entry’
arch/arm/kernel/ptrace.c:922:23: error: ‘AUDIT_ARCH_ARMEB’ undeclared (first use in this function)
arch/arm/kernel/ptrace.c:922:23: note: each undeclared identifier is reported only once for each function it appears in
make[1]: *** [arch/arm/kernel/ptrace.o] Error 1

The issue created by commit:
29ef73b7 Kernel: Audit Support For The ARM Platform

We need to include the linux/audit.h header to the arch/arm/kernel/ptrace.c
file to be able to compile the kernel.
