Eric van Gyzen 4d5a108409 Prevent kernel stack disclosure in signal delivery
On arm64 and riscv platforms, sendsig() failed to zero the signal
frame before copying it out to userspace.  Zero it.

On arm, I believe all the contents of the frame were initialized,
so there was no disclosure.  However, explicitly zero the whole frame
because that fact could inadvertently change in the future,
it's more clear to the reader, and I could be wrong in the first place.

Security:	similar to FreeBSD-EN-18:12.mem and CVE-2018-17155
