scripts: Tweaked mdir/shrub address printing

Browse Source 
This fixes an issue where shrub trunks were never printed even with
-i/--internal.

While only showing mdir/shrub/btree/bptr addresses on block changes is
nice in theory, it results in shrub trunks never being printed because
the mdir -> shrub block doesn't change.

Also checking for changes in block type avoids this.
