Log Message:
(cad/klayout) Fix runtime stream format read, converted install dir.

Previous PKGREVISION did not install plugins, so that reading file may give
unsupportted format error etc. Installing more files now. Because of this
the directory is now under ${PREFIX}/lib/klayout/. The error was originally
reported from Atsushi Toyokura by personal communication, thanks.
(The problem was since 26.*, probably), PKGREVISION++.
