    build: Let Meson fill out the pkg-config directories
    
    There's no need for us to define variables for prefixes, exec prefixes,
    and datarootdirs: those are just a bunch of stuff that got cargo-culted
    in the early days of pkg-config, when integrators had to work around bad
    projects that hard coded their prefixes into the pkg-config file.
    
    Meson already fills out the prefix, bindir, libdir, and datadir
    variables with appropriate values that can be expanded and overridden.
