The problem appeared in Staging a couple days ago: when running 'winecfg' to
create a new prefix or update an existing one, winecfg crashes and the 'Drives'
tab is blank showing an error: Failed to connect to the mount manager; the
drive configuration cannot be edited.

According to the regression test I performed between upstream Wine and
Wine-Staging the Staging patch to blame:

The first upstream commit when the bug appears:

mountmgr: Move the DBus support to the Unix library.
