wip:espeak-ng: ready for pkgsrc

[adr <adr%sdf.org@localhost>]

Hi, I found what was causing the delay in espeak-ng: fifo_stop()
in espeak_ng_Cancel(). Calling audio_object_flush() before, not
after, solves the issue. This is the last dependency of emacspeak.
Could somebody import the port to pkgsrc? I contacted upstream and
it's pkglint clean. I've attached a patch to describe the sonic
option.

Regards.

adr.
