Allow language modules to be installed in the right place.

For Python, ensure the use of the vendor-packages directory, as well as the
use of a 64-bit-specific directory, as needed.

For Lua, the appropriate variable will need to be set during installation,
since there's no corresponding config_lua.lua file.

This is an in-house patch, but has not been passed upstream because it's
against a version of graphviz that is out of date; submission will be
reconsidered when we upgrade.  Note that at least the Python portion is
Solaris-specific, and likely will not be accepted.
