guix: inferior: Fix the behaviour of open-inferior #:error-port.fix-open-inferior-error-port
This should be the error port used by the inferior process, but currently it's
either stderr if #:error-port is a file port, or /dev/null otherwise.
I'm looking at this as the Guix Data Service uses this behaviour to record and
display logs from inferior processes.
* guix/inferior.scm (open-bidirectional-pipe): Call dup2 for file descriptor
2, passing either the file number for the current error port, or a file
descriptor for /dev/null.
