tools lib traceevent: Handle INVALID_ARG_TYPE errno in pevent_strerror

gcc on f14 32-bit rightly complains:

   tools/lib/traceevent/event-parse.c:5097:2: error: enumeration value ‘PEVENT_ERRNO__INVALID_ARG_TYPE’ not handled in switch

The entry for it is in the error strings array pevent_error_str[]:

        _PE(INVALID_ARG_TYPE,   "invalid argument type")

It was just not being handled on the pevent_strerror switch, fix it.
