Subject: [PATCH v2 0/1] arm64: make a single hook to syscall_trace() for all syscall features

This patch makes it easy to add syscall related hooks, including ftrace,
audit and seccomp, in syscall_trace() later.
Those features will be implemented in separate patchsets, but it's safe to
check for all TIF_* now because they can not be turned on anyway.

Changes v1 -> v2:
* added a guard against TIF_SYSCALL_TRACE at tracehook_report_syscall_*()
* renamed _TIF_WORK_SYSCALL to _TIF_SYSCALL_WORK
