Simplify logic to select correct opencascade parameters, due to removal
of slot 7.4.0
use default CMAKE_INSTALL_PREFIX (/usr) instead of /usr/$(get_libdir)/${PN}.
This leads to some files being installed in /usr/{Ext,Mod}. A new patch
fixes this. The lower case symlinks to the executables are no longer
installed now, as the binaries are in the path and can be called directly.
