tracing: Add ftrace event call parameter to its field descriptor handler
Add the struct ftrace_event_call as a parameter of its show_format() callback. This way we can use it from the syscall trace events to retrieve the syscall name from the ftrace event call parameter and describe its fields using the syscalls metadata.
