advisor,errtracker: use upstream bolt package

Upstream snapd uses a fork of the bolt package that carries additional
patches for bugs that were discovered by snapd developers. Bolt itself
appears to be an abandoned project and is not accepting any new patches.

In various distributions the upstream bolt package may or may not have
been patched but the forked version was definitely not packaged. As
such, to build snapd in Debian the upstream bolt package name must be
used.
