Jann Horn 5bf2a45e33 selftests/seccomp: Don't call read() on TTY from background pgrp ...

commit 2bfed7d2ff upstream.

Since commit 92d25637a3 ("kselftest: signal all child processes"), tests
are executed in background process groups. This means that trying to read
from stdin now throws SIGTTIN when stdin is a TTY, which breaks some
seccomp selftests that try to use read(0, NULL, 0) as a dummy syscall.

The simplest way to fix that is probably to just use -1 instead of 0 as
the dummy read()'s FD.
