powerpc: add little endian flag to syscall_get_arch()
Since both ppc and ppc64 have LE variants which are now reported by uname, add that flag (__AUDIT_ARCH_LE) to syscall_get_arch() and add AUDIT_ARCH_PPC64LE variant. Without this, perf trace and auditctl fail. Mainline kernel reports ppc64le (per a058801) but there is no matching AUDIT_ARCH_PPC64LE. Since 32-bit PPC LE is not supported by audit, don't advertise it in AUDIT_ARCH_PPC* variants.
