libpng15_compat: only install shared libraries

Removing the includes inhibits building with the outdated
libpng15.

Be aware that some (also outdated) projects won't compile
anymore if the build 'requires' libpng15. This is caused
by packages that still refer to libpng15 in their
pkgconfig/*pc files.
