Use 2nd stack for update signature verification (#7149)
* Use 2nd stack for update signature verification

Fixes #7145

When doing a signed update, the signature calculation can use a lot of

Also fix a memory leak of signature-bytes found by @JiriBilek

* Reset state on any error condition in Updater::end
