A submission of memtest86+ to Factory makes installation-images fail to build:

https://build.opensuse.org/request/show/1155821

The relevant change in there is:
+- don't install files in /boot. The OS needs to stay in /usr

This in turn makes i-i fail with:

[  244s] adding package memtest86+ [7.00-1.1.x86_64] {postin}
[  244s] cp: cannot stat '/usr/src/packages/BUILD/installation-images-17.116/tmp/cache//memtest86+/rpm//boot/memtest.bin': No such file or directory
[  244s] mk_image: failed to move /boot/memtest.bin to /loader/memtest at lib/AddFiles.pm line 646 in data/boot/boot.file_list line 18.
[  244s] make: *** [Makefile:157: boot] Error 1
[  244s] error: Bad exit status from /var/tmp/rpm-tmp.rMvCg3 (%build)

Seems i-i needs to catch up and copy the file from its new location
