support/scripts: use show-info to extract dependency graph

Browse Source 
Currently, we extract the dependency graph from the aptly named but
ad-hoc show-dependency-graph rule.

We now have a better solution to report package information, with
show-info.

Since show-dependency-graph never went into a release so far, and
show-info does provide the same (and more), switch to using show-info.

Thanks to Adam for suggesting the coding style to have a readable code
that is not ugly but still pleases flake8. Thanks to Arnout for
suggesting the use of dict.get() to further simplify the code.

Note: we do not use the reverse_dependencies field because it only
contains those packages that have a kconfig option, so we'd miss most
host packages.
