perf trace: Add "sendfile64" alias to the "sendfile" syscall

We were looking in tracefs for:

  /sys/kernel/debug/tracing/events/syscalls/sys_enter_sendfile/format when

what is there is just

  /sys/kernel/debug/tracing/events/syscalls/sys_enter_sendfile/format

Its the same id, 40 in x86_64, so just add an alias and let the existing
logic take care of that.
