Subject: [PATCH 2/9] um: drivers/xterm.c: fix a file descriptor leak

From: Jonathan Neuschäfer <j.neuschaefer@....net>

I could use out_close1, but that seems to be the code path to close the
fd returned by os_create_unix_socket, and using it to close the fd
returned by mkstemp might lead to some confusion, so I don't do it.
