What a mess. Changing the package name from libsane to libsane1 and
then expecting nothing breaks??? The Provides: libsane is absolutely
required until all depending packages have been updated to require the
new libsane1 package.
The issue with third party package does not end there. A lot of them
were created before "multi-arch" so they install in /usr/lib/sane or
/usr/lib64/sane, not in some really architecture dependent place such as
/usr/lib/x86_64-linux-gnu/sane. There is little change that third party
*vendor* packages will be rebuilt to fix this.
As far as iscan and its interpreters are concerned, to the best of my
knowledge they are no longer actively maintained. Good luck prodding
EPSON in fixing this.

Actually, I'd leave them where they are and create symlinks to them from
where they are expected. After moving them back to /usr/lib/sane
ln -s ../../sane/libsane-epkowa.la
ln -s ../../sane/libsane-epkowa.so.1
ln -s ../../sane/libsane-epkowa.so.1.0.15

You shouldn't have to reboot. Just restart your application.

Like I said, good luck with that.
Hope this helps
