profile.mk: defer RC expansion

Just spotted that .disk/profile.tgz would hold distcfg.mk with pre-expanded $(HOME) from build host which is both info leak (user account that was used to build the particular image) and just wrong given that the in-image profile archive was conceived as a means to pass that part of build environment over instead of tying it to vendor. Morale: premature optimization is premature.
