Also, fix a bug in common code that could cause other tests to fail: using
ppoll(2) in combination with buffered I/O for /dev/auditpipe. Fix it by
disabling buffering.

Tested syscalls include rfork(2), chdir(2), fchdir(2), chroot(2),
getresuid(2), getresgid(2), setpriority(2), setgroups(2), setpgrp(2),
setrlimit(2), setlogin(2), mlock(2), munlock(2), minherit(2), rtprio(2),
profil(2), ktrace(2), ptrace(2), fork(2), umask(2), setuid(2), setgid(2),
seteuid(2), and setegid(2). The last six are only tested in the success
case, either because they're infalliable or a failure is difficult to cause
on-demand.
