    Update installer script for restructured scheme files
    
    lib/gnucash/scm is used for gnucash 3.x
    lib/guile/2.2/site/ is the new location starting with gnucah 4.x
    
    As the same build scripts are used for both series, make the
    old path optional. Note this may require a clean build for
    master to get right.
