Avoid deploying skeletons inside a directory

We had to switch to recursive mode so that we can control more precisely
what gets installed.

src/include/deploy.sh

     local src=$1                            # source path
     local dst=$2                            # destination path
     local mode=${3:-$MKIT_DEFAULT_MODE}     # mode
-    local chmod_item                        # each file to chmod in directory
+    local item                              # each in directory
     if test -d "$src"; then
-        _maybe mkdir -vp "$(dirname "$dst")"
-        _maybe cp -Tvr "$src" "$dst"
-        find "$dst" -type f \
-          | while read -r chmod_item; do
-                _maybe chmod "$mode" "$chmod_item"
+        find "$src" -type f \
+          | while read -r item; do
+                [[ $item =~ .skel$ ]] \
+                 && grep -q "${item%.skel}" "$MKIT_LOCAL/built.lst" \
+                 && continue
+                _deploy_item "$item" "$dst${item#$src}" "$mode"
             done
     else
         _maybe install -DTvm "$mode" "$src" "$dst"
