    build: Fix exec_prefix variable
    
    The `exec_prefix` variable inside the pkg-config file is pointing to
    `libexecdir` but it should be pointing to prefix instead.
    
    This has been changed so `exec_prefix` points to the proper path.
    
    The `libexecdir` meson variable has also been removed because the
    only the `pkglibexecdir` variable is used.
