erlang_release: "failed to cleanup output directory" when setting `include_erts = True`

[f-f]

As per title - setting include_erts = True in a erlang_release declaration causes errors in subsequent rebuilds: when the cache is invalidated, or when calling buck2 clean, buck2 will try to remove the output directory, and fail to do so. This is likely because the erts folder in the release is not included with writing permissions:

$ ls -alh buck-out/v2/gen/root/200212f73efcd57d/__my-release__/__build/erlang-local/my-app/

Hi, sorry for the late answer. I just tried to reproduce the issue locally, but have the same permissions set for erts/ then any other folder. The rules just copy the erts folder from the Erlang distribution used during the build into the release output folder. Can you check the permissions on that folder? We could chmod the folder to add write priviledges to avoid the issue as well.
