wineinstall patch

[Chris Morgan]

This patch has some significant changes to wineinstall, the most notable 
being that we no longer let the user run wineinstall as root user and that we 
use su -c"command" to run 'make install' and to modify the users 
/etc/ld.so.conf file if necessary.  I wanted to get feedback from people on 
these changes.

Thanks,
Chris

Prevent the user from running wineinstall as root, add script commands so 
we 'su root' for installing and other commands that require root 
access.  Fix modification time comparison of wrong file.  Added 
missing sed line. Always 'make ' before we run make install so 
no build files become owned by root.
