[ Upstream commit 0528904926aab19bffb2068879aa44db166c6d5f ]

Running evemu-record on the lid switch event shows that the lid reports
the first "close" but then never reports an "open".  This causes systemd
to continuously re-suspend the laptop every 30s.  Resetting the _LID to
"open" fixes the issue.
