#6 Include /opt and /lib32 in mapprefix and exeprefix

[Pacho Ramos]

Default /etc/preload.conf is missing /lib32 dir (used in amd64 arch for 32 bits libs) and /opt (used by some apps)

Simply adding them to proper entries in conf maked preload to also prefetch files from this locations

The attach patched fixes this

Thanks a lot
