[RFC PATCH v2 4/7] csu: Fix standard fds' mode

[Sergey Bugaev]

stdin is supposed to be readable, stdout and stderr writable. Otherwise,
we get this:

l-wx------. 1 root root 64 Apr 19 18:40 0 -> /dev/full
lr-x------. 1 root root 64 Apr 19 18:40 1 -> /dev/null
lr-x------. 1 root root 64 Apr 19 18:40 2 -> /dev/null
