[Rpm-maint] [rpm-software-management/rpm] RFC: Use an erase element to delete packages with same NEVRA (#770)

Rpm used to rely on the "replacepkgs hack" to get rid of the old
header entry when reinstalling a package. This has a number of
problems when the headers are not identical or different
install flags were used.

To mitigate this, a '--reinstall' option was added that made rpm
use an erase element in this case.

This commit takes this one step further by changing the code to also
use an erase element in the --upgrade case. The code is mostly simpler,
but we need a different implementation for commit fd40d58efa, as we now
have erase elements both for --reinstall and --upgrade. Thus we
need to store the addop in the transaction element.

The commit does not change the behaviour of 'rpm --install'.
