This extends list of fields checked for reinstall to not only Version
but also to Architecture, LinkSignature, Depends, Conflicts, Provides.

There are two reasons why we want to have these:

First reason applies on Architecture, Depends, Conflicts and Provides.
Those trigger update to get package information in sync with repository.
Updater runs planning against repository so this has no effect but in
the end if someone forgets to bump package but modifies dependencies for
example then we reinstall package anyway.

Second reason to reinstall package applies on LinkSignature and that is
field inserted with hash generated from dynamic linker information
collected for package. When this hash changes then link dependencies
changed and even if version is same we have to reinstall such package as
it most probably won't work with updated dependencies.

As a tinny bonus logs now contain info about version or any other field
if the differ and that way info about the reason to reinstall given
package.
