package/babeld: update URL site

As reported in [1], version 1.9.2 has been moved to another archive, and
it is recommended to use https://github.com/jech/babeld as the official
repository.

The use of the github macro:

$(call github,jech,babeld,babeld-$(BABELD_VERSION))

would have downloaded a file with the same name (e.g. babeld-1.9.2.tar.gz)
but with a different hash from the one downloaded from the previous URL,
creating unacceptable backward compatibility issues.
Therefore, it was decided to download the package via the git method. In
this way, the downloaded file is babeld-babeld-1.9.2-git4.tar.gz, thus
with a different name, to which its SHA can be associated without side
effects, except for breaking the release monitoring process.
Unfortunately, for now, we will have to live with this limitation.

Particularly interesting are the explanations provided by Yann E. Morin,
which you can find in [2], that guided the creation of this patch.
