perf parse: Allow tracepoint names to start with digits

Tracepoints can start with digits, although we don't have many of these:

  $ rg -g '*.h' '\bTRACE_EVENT\([0-9]'
  net/mac802154/trace.h
  53:TRACE_EVENT(802154_drv_return_int,
  ...

  net/ieee802154/trace.h
  66:TRACE_EVENT(802154_rdev_add_virtual_intf,
  ...

  include/trace/events/9p.h
  124:TRACE_EVENT(9p_client_req,
  ...

Just allow names to start with digits too so e.g. "perf trace -e '9p:*'"
works
