math/R: Do not specify minimum tk version

Specifying TCLTK_USES=tk:84+ was pulling in version 8.4 for package builds on
cluster, however the Tcl/Tk 8.4 ports are being deprecated.  Simply using
TCLTK_USES=tk pulls in the default version. [1]

While here, silence a portlint warning about the location of ONLY_FOR_ARCHS and
use DISTVESION instead of PORTVERSION.
