Refactor the syscall table into a shared location

The ftrace trace processor had this mapping in order to convert the
syscall ids found in ftrace logs to proper names. A new feature is being
added that allows filtering syscalls during tracing. It will need to
convert string names into numbers within traced_probes.

Test: ran perfetto_unittest
