compat_sunos32: Memset zero before copyout.

Unclear if this can leak anything but let's be on the safe side.

compat_ossaudio: Zero-initialize idat before copyout.
Unclear if there are any paths to the copyout without initialization,
but let's play it safe to keep the auditing effort low.

linux32_rt_sendsig: Memset zero before copyout.
Not sure if there's any padding here, but it's a pretty big
structure, fairly likely, so let's be rather safe than sorry.
