[patch] add missing pledge to aucat(1).

[Jesper Wallin]

Hi all,

I just noticed that aucat(1) is missing pledge.  However, I'm aware that
aucat(1) is talking to sndiod(8), which is being pledged properly.  But
seeing that programs like yes(1) is properly pledged, I don't see any
reason not to pledge aucat(1) as well, unless I'm missing something
obvious.


Regards,
Jesper Wallin
