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

Acked-by Andrew Cooper <andrew.cooper3@citrix.com>, although as we're
trying to keep on top of the changelog this time around, we probably
want the following hunk:

I'm fine with the additional CHANGELOG.md change.
I thought the suggested addition is obvious.

Thanks, but as I'm folding it into your patch, I shouldn't do it
unilaterally without someone else saying ok.

As it happens, Wei offered his A-by on IRC for the change, so I'll go
ahead as suggested.
