[PATCH v6 16/30] objtool: Do not validate IBT for .return_sites and .call_sites

[Alexandre Chartre <alexandre.chartre@oracle.com>]

The .return_sites and .call_sites sections reference text addresses,
but not with the intent to indirect branch to them, so they don't
need to be validated for IBT.

This is useful when running objtool on object files which already
have .return_sites or .call_sites sections, for example to re-run
objtool after it has reported an error or a warning.
