ssh: Pass an empty "exceptfds" set to 'select'.
Previously the redirect code could end up exiting prematurely because of
an uninteresting "exceptional condition" on the socket (info "(libc)
Waiting for I/O").
* guix/ssh.scm (remote-daemon-channel): Pass the empty list as the third
argument to 'select'. It was a mistake to pass a non-empty list there
in the first place.
