sqlite3: cleanup configure feature flags for better maintenance

* PKGBUILD:
  - prefer configure flag '--enable-all' which comprises
    --enable-json1, --enable-fts4, --enable-fts5
  - add configure flag --enable-rtree and remove CPP flag '-DSQLITE_ENABLE_RTREE=1'
    (NB: In sqlite 3.32.3 --enable-rtree is not implied by --enable-all in
    contrast to the documentation. Once this bug is fixed --enable-rtree
    can be removed here.)
