In commit 529fef57f6 ("package/bird: add
optional protocols") we added options to conditionally enable
different protocol support. However, disabling the RIP support was not
working, so it remained forcefully enabled, and there was no
BR2_PACKAGE_BIRD_RIP option.
However, since the bump to 2.0.6 in commit
b9f43ade0f, this issue has been fixed,
so we can introduce the BR2_PACKAGE_BIRD_RIP option, and make it
really optional.
