starmath: Drop ENABLE_DEBUG_DUMPASDOT feature

The feature for debugging seems unused so long that defining
ENABLE_DEBUG_DUMPASDOT breaks the build but no one complains.
So let's ditch it.

-#    Watches for formula dumps by starmath and renders them
-# If starmath is compiled with the macro DEBUG_ENABLE_DUMPASDOT defined.
-# shift+enter, in the visual formula editor will make starmath dump a
-# graphviz graph of the formula tree structure. This is very useful when
-# debugging. The formula is dumped to /tmp/smath-dump.gv-
-# This script monitors this file and renders the graph when written,
-# after which the formula is displayed using feh.
-#
-# Usage: Let this script run in the background, e.g. start it in a terminal
-# (and don't close the terminal). Then compile starmath with DEBUG_ENABLE_DUMPASDOT
-# defined, use the visual formula editor to write something and hit shift+enter.
