[mutter/wip/fmuellner/fix-pc-location] build: Install .pc files in correct location

    build: Install .pc files in correct location
    
    If a library is provided in the positional arguments, then meson
    defaults to installing the .pc file in a 'pkgconfig' subdirectory
    in the library's install location. We want the files in the regular
    $libdir/pkgconfig rather than $libdir/mutter-$api/pkgconfig, so
    specify the location explicitly in the parameters.
