Revert "policycoreutils: let output of fixfiles be redirected (as normal)"

This reverts commit ac7899fc3a,
which is not yet part of an officially tagged release
(or release candidate).

`LOGFILE=/proc/self/fd/1` was wrong.

`LOGFILE=$(tty)` was being relied on in one case (exclude_dirs),
to log messages from a function run specifically with stdout redirected
(captured into a variable).

Having `logit "message"` break inside redirected functions
is a nasty leaky abstraction.

This caused e.g. `fixfiles restore` to terminate early with the error

    skipping: No such file or directory

if the user had configured any excluded paths in
/etc/selinux/fixfiles_exclude_dirs
