This is useful to silence output in forked programs:
https://bugzilla.redhat.com/show_bug.cgi?id=1287918
Tested with the following scriptlet:
```
%post -p <lua>
pid = posix.fork()
if pid == 0 then
assert(posix.exec("/bin/sed"))
elseif pid > 0 then
posix.wait(pid)
end
pid = posix.fork()
if pid == 0 then
posix.close(2)
io.open("/dev/null")
assert(posix.exec("/bin/awk"))
elseif pid > 0 then
posix.wait(pid)
end
```
As expected, the error message from sed is printed, the error message
from awk is not.
