arm64: fix AUDIT_ARCH_AARCH64ILP32 bug on audit subsystem

bugzilla: 174525 https://gitee.com/openeuler/kernel/issues/I8JVJ3



--------

In arm64be_ilp32 platform, audit could not record log in some case, because
syscall_get_arch() in arch/arm64 returns AUDIT_ARCH_AARCH64ILP32, which
fits the arm32 platform. Audit will gets a fault arch in this
situation and hence mismatch some syscall numbers in audit_match_perm().

This patch fixes it, and use the arch AUDIT_ARCH_AARCH64 which matches
all syscall numbers in arm64be_ilp32 platform.
