depgraph: Don't ignore downgrades as missed_updates
Missed updates can also come in the form of package downgrades,
when, for example, there are keyword changes. They can cause
rebuilds, and these rebuilds may be not possible due to reasons such
as keywords or masks. In this case, prior to this patch, portage
would cancel the downgrade, but the rebuilds would be requested
endlessly, because bug 439688's backtrack code does not trigger.
To reproduce, on an ACCEPT_KEYWORDS=~amd64 machine, emerge
=dev-libs/openssl=3.0.9, dev-util/rustup, and something else that
depends on openssl. Then un-accept ~amd64 for openssl and rustup.
Prior to this patch, a @world upgrade would cause:
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild rR ] dev-libs/libevent-2.1.12-r1:0/2.1-7::gentoo
[ebuild rR ] net-misc/rsync-3.2.7-r2::gentoo
[...]
Total: 71 packages (71 reinstalls), Size of downloads: 0 KiB
There are no packages marked "R", only "rR". There are no section
labeled "The following packages are causing rebuilds:" either.
After this patch, we have:
These are the packages that would be merged, in order:
Calculating dependencies... done!

WARNING: One or more updates/rebuilds have been skipped due to a dependency
conflict:
dev-libs/openssl:0
(dev-libs/openssl-1.1.1u:0/1.1::gentoo, ebuild scheduled for merge)
dev-libs/openssl:0/3= required by (dev-util/rustup-1.25.2:0/0::gentoo,
installed)
I also updated the test from the previous patch to account for
this change. No other tests seems affected.
