fixing VAPIGEN_MAKEFILE to work with dev-lang/vala-common.

# @BLURB: Sets up the environment for using a specific version of vala.
# @DESCRIPTION:
# This eclass sets up commonly used environment variables for using a specific
# version of dev-lang/vala to configure and build a package. It is needed for
# packages whose build systems assume the existence of certain unversioned vala
# executables, pkgconfig files, etc., which Gentoo does not provide.
#
# This eclass provides one phase function: pkg_setup.
