Use vpath instead of VPATH.

Usage of VPATH makes troubles when used within $(builddir).
Not only source files are being found through VPATH,
but targets as well. (make --debug=v)

Thus if user builds the code in $(srcdir) and also in some $(builddir)
he gets mangled results as some generated files (i.e. .export.sym)
are 'reused' from $(srcdir) instead of $(builddir).

This patch switches to use vpath were we could explicitly name
suffixes that should be looked via vpath - we must take care,
we do not generate files with these suffixes:
.c, .in, .po, .exported_symbols

 Version 2.02.63 -  
 ================================
+  Switch from using VPATH  to vpath in Makefiles.
   Permit mimage LVs to be striped in lvcreate and lvresize.
   Fix pvmove allocation to take existing parallel stripes into account.
   Add pvmove_source_seg to struct lv_segment.
