[kbd] [PATCH] src/openvt.c: Close fd0 in parent after child has returned

[Michael Schutte]

The race condition fix (commit 9d987…) introduces a regression which
causes the parent to leave open the file descriptor pointing to the VT
opened.  This causes VT_DISALLOCATE to fail with an EBUSY error.

Fixed by closing fd0 in the do_wait stanza.
