repo: Use separate task for patching repo rev

Using a task instead of a version specific patch for setting the repo
revision within the source code. This drastically decreases the
maintenance burden and easier usage of the OE update helper.

-Subject: [PATCH] Set REPO_REV to v2.17.3
-
-repo is an unusual tool because it downloads all of its own Python modules
-using GPG-signed git tags, and stores those files as part of the project
-that it is working with.
-
-So in order to have a reproducible repo installation within the project
-folders, we hardcode the default REPO_REV to a SHA1 that corresponds to
-the version of the recipe. REPO_REV can still be overwriten by the user,
-by specifying the REPO_REV environment variable.

-Upstream-Status: Inappropriate [configuration]
