Fix LOAD.18 on non-Windows by ensuring that *LOAD-TRUENAME* contains one.

A bit of a hack by doing this in Load.java, as it should already have
been passed through the TRUENAME routines by the time things get here,
but the code needs a more thorough re-working anyways.

Refactor probe_file.java Lisp interfaces to have public access and
obey current conventions.
