Subject: syscall: disable TestAllThreadsSyscall on linux-ppc64
X-Git-Tag: go1.16beta1~553

syscall: disable TestAllThreadsSyscall on linux-ppc64

For some reason, currently unknown, this test case fails exclusively
on the linux-ppc64 platform. Until such time as it can be made to
work, we'll disable this test case on that platform.

The same issue causes TestSetuidEtc to fail too, so disable that
on this platform.

Updates #42178
