commit ba7d32270a83b16d8b2d696287f9b0ea5ca4fcc3

    build: Let Meson fill out the pkg-config directories
    
    There's no need for us to define variables for prefixes, exec prefixes,
    and datarootdirs.
    
    Meson already fills out the prefix, bindir, libdir, and datadir
    variables with appropriate values that can be expanded and overridden.
