entry: Add arch_ptrace_report_syscall_entry/exit()

Browse source

ARM64 requires a architecture specific ptrace wrapper as it needs to save
and restore scratch registers.

Provide arch_ptrace_report_syscall_entry/exit() wrappers which fall back to
ptrace_report_syscall_entry/exit() if the architecture does not provide
them.

No functional change intended.
