feat: preinstall plocate for faster file locating

plocate is a fast and efficient file locating tool that improves upon
the traditional locate command. Database is updated daily or on demand
by running `sudo updatedb`, then users can quickly find files using
`locate <filename>` -- much faster than using `find` across the
filesystem.
