Make the updatedb script installed as /usr/libexec/locate.updatedb

inspect all local file systems, not only ufs and ext2fs. A number
of local file systems has been added over time, and at least zfs
has the potential to become a popular choice. Without this change
a ZFS root file system causes the script to ignore all file-systems
and leads to an empty locate db. (An alternative is to add all the
relevant file systems individually, which means that at least zfs,
xfs, ntfs, ntfs-3g, msdosfs should be added, probably more).
