Fixed typoo.

* glibtop_private.h: Fixed typoo.

        * procmap.c (glibtop_get_proc_map_s): Implemented start, end,
        offset and perm for mapped segments. File name and inode
        should be accessible from bunyip kstat data. The only
        obstacle is that the data format is undocumented and
        possibly not the same accross releases.
