Why I did it
After a build ./src/sonic-frr/frr was always marked as "modified". This changeset resets it to the way it was before the build.
Resolves: #20869
How I did it
The sonic-frr/Makefile had steps to apply stg (and other) patches. Now a checkout to the original branch is done at the end, and other cleanup is done at the start.
How to verify it
Run:
Observe how ./src/sonic-frr/frr is unchanged afterwards. The patched version is still available in a stored stg_temp branch.
Which release branch to backport (provide reason below if selected)
^- also relevant for 202405 branch (needs slight change)
Tested branch (Please provide the tested image version)
