Michael Ellerman 1b60bab04e powerpc/kernel: Add SIG_SYS support for compat tasks 
SIG_SYS was added in commit a0727e8ce5 "signal, x86: add SIGSYS info
and make it synchronous."

Because we use the asm-generic struct siginfo, we got support for
SIG_SYS for free as part of that commit.

However there was no compat handling added for powerpc. That means we've
been advertising the existence of signfo._sifields._sigsys to compat
tasks, but not actually filling in the fields correctly.

Luckily it looks like no one has noticed, presumably because the only
user of SIGSYS in the kernel is seccomp filter, which we don't support
yet.

So before we enable seccomp filter, add compat handling for SIGSYS.
