[PATCH] simpletrace: build() missing 2 required positional arguments

["Volker Rümelin" <vr_qemu@t-online.de>]

Commit 4e66c9ef64 "tracetool: add input filename and line number to
Event" forgot to add a line number and a filename argument at one
build method call site.

Traceback (most recent call last):
  File "./scripts/simpletrace.py", line 261, in <module>
    run(Formatter())
  File "./scripts/simpletrace.py", line 236, in run
    process(events, sys.argv[2], analyzer, read_header=read_header)
  File "./scripts/simpletrace.py", line 177, in process
    dropped_event =
      Event.build("Dropped_Event(uint64_t num_events_dropped)")
TypeError: build() missing 2 required positional arguments:
  'lineno' and 'filename'

Add the missing arguments.
