Revert "opendingux: GCW0: Symlink ~/.local ~/.config to /usr/local /usr/local/etc"

It's a bad idea to mix per-user configs and system-wide configs.

This reverts commit 6a42905dfdbe30fe7bccc32adee6267d9abd55a2.
opendingux: GCW0: Remove the tvtool / tvout_config utilities

Those are specific to the A320 version of OpenDingux.
opendingux: GCW0: Use /usr/local/etc instead of /etc/local

The former is distribution-agnostic and should be used instead.
