gdata: retire recipe. (#8228)

Reasons:
- Was for Python 2.7 only (and we're using 3.9 as default).
- Not required by anything in-tree.
- Last release in 2013, last commit in 2016, and Google has archived
  (made read-only) the repo in Dec 2022.

For kicks: it supports things like Google Notebook API, which Google
killed ages ago :-)

-SUMMARY="Python client library for Google data APIs"
-DESCRIPTION="
-The Google Data APIs (Google Data) provide a simple protocol \
-for reading and writing data on the web. Though it is possible \
-to use these services with a simple HTTP client, this library \
-provides helpful tools to streamline your code and keep up with \
-server-side changes.
