Yann E. MORIN eb342619e1 core/show-info: also export source and stamp directories in show-info
External tools may need to peek into the source tree (to check what the
list of patches that were applied), or in the stamp directory (to check
and report on the progress of a build)

Currently, both locations are identical, but semantically different
and an internal implementation detail. Exposing both separately will
allow us to change either without breaking users' scripts. Hopefully.
