[RFC/PATCH] config.mak.in: remove unused definitions

[Junio C Hamano]

When 5566771 (autoconf: Use autoconf to write installation
directories to config.mak.autogen, 2006-07-03) introduced support
for autoconf generated config.mak file, it added a few "export",
in addition to definitions of srcdir and VPATH.

These "export" logically does not belong there.  The common make
variables like mandir, prefix, etc, should be exported to submakes
for people who use config.mak and people who use config.mak.autogen
the same way, so if we want to get these exported, that should be in
the main Makefile, no?

We do use mandir and htmldir in Documentation/Makefile, so let's
add export for them in the main Makefile instead.

We may eventually want to support VPATH, and srcdir may turn out to
be useful for that purpose, but right now nobody uses it, so it is
useless to define them in this file.

 * As everybody knows, I do not use autoconf/configure, so this may
   be breaking things for those who do.  Comments, objectsions, and
   general education etc. are very much appreciated.
