factory/build: restore out-of-tree build support
When attempting an OOT build, it fails to find <factory/cplusplus.h>,
because cplusplus.h is always (even in in-tree builds) produced in
"${builddir}", and not "${top_srcdir}/../factory".
Furthermore, one must not rely on the basename of ${top_srcdir}, and
going above ${top_srcdir} is undefined and may lead to spurious build
failures. (Consider a hypothetical chroot on ${top_srcdir}).
Therefore, create a directory include/factory and use -Iinclude such
that <factory/*> yields a buildable state, move all exported header
files there.
