[PATCH 6/9] lei_store: give process a better name

[Eric Wong <e@80x24.org>]

We'll prioritize the last two components of the path name
("lei/store") since that's how I often refer to the on-disk
location.  Then, show the XDG_DATA_HOME it belongs to in case
a user changes HOME or XDG_* for testing purposes.
