Verified 1.10ubuntu5.1 on Disco.
Discos' 1.10ubuntu5 already had the fix to not fall back to mark all
upgradable packages, it just received follow-up commits to all kinds of
dependencies and skip held packages earlier.

Bug description:
[Impact]
* The fix for LP: #1821101 allowed installing packages for which
APT's resolver could not find solution for without adjusting other
packages, but also tries to adjust many packages to install packages
which are held back.
[Test Case]
* Set up a system where systemd (or a package that can't be upgraded
without also upgrading other packages) need to be upgraded to the
version in -security.
* Mark systemd on hold
apt-mark hold systemd
* Observe u-u falling back to adjusting all upgradable packages in
unfixed versions and adjusting only a few in fixed versions:
# unattended-upgrade --verbose --debug
...
adjusting candidate version: libnss-systemd=237-3ubuntu10.19
falling back to marking libnss-systemd, then adjusting changes
package libnss-systemd upgradable but fails to be marked for upgrade
(E:Unable to correct problems, you have held broken packages.)
falling back to adjusting all packages
adjusting candidate version: 2ping=4.1-1
...
Fixed:
...
adjusting candidate version: libnss-systemd=237-3ubuntu10.19
falling back to adjusting libnss-systemd's dependencies recursively
adjusting candidate version: libnss-systemd=237-3ubuntu10.19
adjusting candidate version: libkmod2=24-1ubuntu3
adjusting candidate version: mount=2.31.1-0.4ubuntu3
adjusting candidate version: libmount1=2.31.1-0.4ubuntu3
...
[Regression Potential]
* The less extensive fallback may not find solutions for installing
packages with special relationships that the full fallback could have
found, but I don't know about such special cases in the archive and
the autopkgtest cover a fair set of popular packages. Keeping back
those packages seems to be better than spending a lot of CPU time on
finding a few solutions - which still was not enough to find _all_
solutions.
