[PATCH v2] tools: remove unused sysconfig variable XENSTORED_ROOTDIR

[Olaf Hering <olaf@xxxxxxxxx>]

The sysconfig variable XENSTORED_ROOTDIR is not used anymore.
It used to point to a directory with tdb files, which is now a tmpfs.

In case the database is not in tmpfs, like on sysv and BSD systems,
xenstored will truncate existing database files during start.

Fixes commit 2ef6ace428dec4795b8b0a67fff6949e817013de
