geo-rep/libgfchangelog: Create working dir during changelog_register if not present.

Earlier, xysnc's register was being called first,
which was creating working directory before calling
changelog_register. Now it is history crawl first.
Hence working directory would not have been created.
Create it in gf_changelog_register itself if it is
not already created.
