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
