[PATCH] tty: vt: conmakehash: cope with abs_srctree no longer in env

conmakehash uses getenv("abs_srctree") from the environment to strip the absolute path from the generated sources. However since commit e2bad142bb3d ("kbuild: unexport abs_srctree and abs_objtree") this environment variable no longer gets set. Instead use basename() to indicate the used file in a comment of the generated source file.
