gnomeExtensions.dash-to-dock: Build from source again

The stable version has several usability bugs (e.g. https://github.com/micheleg/dash-to-dock/issues/1629)
but patches do not apply cleanly to the zips from the extension portal.
Let’s switch back to building from source to make it easier to update the extension.

This reverts commit 2bb795bab2,
adds an update script and updates to latest git revision.
