Commit aafe8609 "d/postinst: fixup userid for older termproxy tasks"
does the fixup after the upgrade, which is fine for CLI upgrades, but
doesn't work for the GUI, as the termproxy instance used for upgrading
will write it's own tasklog (with the still broken version) after the
upgrade and postinst.

Instead, add a (temporary) workaround to the UPID parser to handle this.

v2:
* don't just match root

As discussed off-list with Dominik, it's debatable if we want this patch
together with the second one, or if the latter is enough on it's own. It does
fix a breakage, but it adds workaround code, and this is a Beta after all...
