Alan Jenkins db14db8479 selinux-autorelabel: remove incorrect redirection to /dev/null
This code is currently incorrect.  Currently redirecting `fixfiles` to
/dev/null will have very little effect.  Two messages will be suppressed,
but both the percentage progress indicator, and any errors from
the setfiles/restorecon binary will still be shown.

The fact that fixfiles redirected its log output to stdin (!) was purely
an implementation artefact.  It was used to write log messages even inside
shell functions whose output is captured e.g. `RESULT=$(shell_func)`.

When fixfiles is fixed to support output redirection normally, this code
would now behave incorrectly.  It would suppress all percentage progress
messages for this long-running process.
