Subject: [PATCH] Revert "Exiv2 is now released with exported targets using
cmake rules. No need to have a dedicated find exiv2 cmake script. Bump
minimal version to 0.27.1"
This reverts commit 06e77271d72fe5e4abeb38641f3addc2cfbff126.
Also, it replaces the use of `Exiv2::XmpData::eraseFamily()` (new in
exiv2-0.27) with inline code copied from exiv2-0.27.5.
Fixes build on Leap 15.x which only have exiv2 0.26.
