graphviz: Do not build tcl support for target

tclpkg looks for tclsh on buildhost and if we try to use the native
version then it groks the paths from the native sysroot and builds and
installs the target tcl packages into the same path, in the end it ends
up being wrongly packaged. Therefore its best to disable tcl

Secondly, package python and perl pieces into independent packages so
the runtime dependencies are also set accordingly.
