System integration scripts use dbus-uuidgen --ensure, so they are
unaffected by this, and in particular the solution to Bug #77941
is still valid.
The shared library is typically loaded by unprivileged users, so
trying to write out the machine-id file is not going to work anyway.
However, if we *can* write to our ${sysconfdir} - notably during
`make distcheck` - then it is unexpected that merely reading the
machine ID has the side-effect of writing to ${sysconfdir},
and in particular it will make the check for a complete uninstall
fail. We definitely must not delete the machine ID during
`make uninstall`.
