Log Message:
Fix installation after USE_BUILDLINK3 was enabled by default:

	* ezm3 installs its files into ${PREFIX}/ezm3, the installation
	  fails due to missing libraries, fixed with
	  BUILDLINK_PASSTHRU_DIRS.
	* Provide a buildlink3 file with DEPMETHOD=build to fix the
	  cvsup packages.

Bump PKGREVISION, this closes PR pkg/29986 and PR pkg/30159.
